- CDPD-125832: Storage Browser file download failure in Data Explorer
- 7.3.3.0
- Previously, file downloads and previews failed when you used the
Storage Browser in Data Explorer behind a Knox gateway. This issue
occurred because generated download and preview URLs omitted the required gateway proxy
prefix, preventing requests from reaching the service. This issue is resolved by
appending the proxy path prefix to download and preview URLs.
- CDPD-125184: Oozie workflow submission failure in Data Explorer
- 7.3.3.0
- Previously, submitting Oozie workflows from the Storage Browser
in Data Explorer failed. This issue occurred because workflow
submission omitted external parameter names. This issue is resolved by preserving
workflow variable parameters, correcting processing, and refining route query parameters
during submission.
- CDPD-124478: Error when accessing the Impala tab in the Jobs
browser
- 7.3.3.0
- Previously, an error occurred when you clicked a query ID in the
editor to open the query profile page if your environment uses an active-passive
coordinator setup. This issue exists as a result of changes made to support
active-active coordinator configurations, preventing access to detailed query metrics in
active-passive environments. This issue is now resolved.
- CDPD-124161: TLS hostname validation failure in Data Explorer
- 7.3.3.0
- Previously, Impala connections in Data Explorer running on Python 3.12 failed TLS hostname validation
when coordinator fully qualified domain names (FQDNs) exceeded 64 characters or when
connections used HAProxy aliases. This issue occurred because hostname validation did
not evaluate Subject Alternative Names (SAN) defined in valid certificates. This issue
is resolved by updating hostname validation logic in Data Explorer
to validate SAN entries on Python 3.12.
- CDPD-123398: Gunicorn server log rotation failure in Data Explorer
- 7.3.3.0
- Previously,
rungunicornserver.log files in Data Explorer rotated prematurely at irregular file sizes well below
the configured 4.8 MB threshold. This behavior caused overlapping timestamps and
fragmented entries across rotated log files. This issue is resolved by improving log
file handling across worker processes to ensure log files rotate at the configured file
size threshold.
- CDPD-101348: Data Explorer administration
UI leads to incorrect URL
- 7.3.3.0
- Previously, the Download logs button in
the Data Explorer administration UI pointed to an incorrect or
outdated URL, which prevented from downloading server logs. This issue is now resolved
by updating the log download API endpoints.
- CDPD-98406: Excessive Gunicorn debug log generation
- 7.3.3.0
- Previously, Gunicorn log listeners generated debug-level records
for access and metrics even when Data Explorer debug mode was
disabled. This behavior caused unnecessary log clutter. This issue is now resolved by
ensuring Gunicorn log output honors the Data Explorer debug mode
setting.
- CDPD-96460: Impala query profile row count display error
- 7.3.3.0
- Previously, the Data Explorer Impala
editor component displayed incorrect row count values for large tables because it
incorrectly parsed the
RowsReturned metric property from the EXCHANGE
node component inside the Impala query profile log. This issue is fixed by implementing
a threshold-based bucketing approach that displays approximate row count indicators,
such as 1000+ rows or 10000+ rows, to prevent
inaccurate query metadata displays.
- CDPD-95948: Orphaned process detection failure in Data Explorer
- 7.3.3.0
- Previously, process cleanup in Data Explorer incorrectly flagged active processes as orphaned, causing valid service processes to
stop unexpectedly during cleanup routines. This issue is resolved by improving the
detection logic to prevent false positives during process management cleanup.
- CDPD-69906: Impala file import failure in Data Explorer
- 7.3.3.0
- Previously, importing files into Impala by using Data Explorer failed on high-speed network connections. This issue
occurred because rapid automated query progression stalled during sequential import
operations, and result size requests were incorrectly triggered for data definition
statements. This issue is resolved by improving query progression handling during
automated imports and bypassing result size checks for statements without active query
handles.
- CDPD-125940: Storage Browser refresh failure in Data Explorer
- Previously, refreshing Amazon S3 directories in the Data Explorer Storage Browser failed. This issue occurred because a
name collision existed between the
fs query parameter in the frontend
and a parameter in the backend middleware. This issue is resolved by renaming the
frontend query parameter from fs to tab.
- CDPD-125833: Zero-byte file upload failure in Data Explorer
- Previously, uploading zero-byte files to cloud storage by using
the Storage Browser in Data Explorer failed with an XML error.
This issue occurred because the upload process initiated multipart upload operations
that Amazon S3 rejects when no parts are submitted. This issue is resolved by writing
zero-byte files through a single put operation instead of a multipart upload, and
removing the zero-byte file size check from the client-side.
