Know more about the behavioral changes in cumulative hotfix 11 for 7.1.9
SP1.
HBase
- Summary:
- Added security headers to the thrift or HTTP server
- Previous Behavior: Previously, security headers were
absent in the responses of Thrift or HTTP servers when utilizing HBase-exposed services.
- New Behavior: To address this, additional security headers
are introduced in the responses of the HBase Thrift server when HTTP or HTTPS transport is
enabled.
Apache Jira: HBASE-27118
Impala
- Summary:
- Batched Insert events for Impala
- Previous Behavior: Impala initiated insert statements
using a single API call for each partition. This could become a performance bottleneck when
inserting data into tables with a large number of partitions.
- New Behavior: This change speeds up computing file
checksums during
INSERT operations, especially for tables with many files and
partitions. This is achieved by leveraging a new batch insert API in the Hive Metastore to
process events more efficiently.Apache Jira: IMPALA-14051
- Summary:
- Support for parquet PageHeaderV2
- Previous Behavior: The parquet scanner did not support
reading or processing of V2 Parquet DataPageHeader.
- New Behavior: The parquet scanner now supports reading of
V2 Parquet DataPageHeader.
Apache Jira: IMPALA-6433
- Summary:
- Faster checksum computation during INSERT
- Previous Behavior: During
INSERT
operations, most of the time was spent fetching file checksums, which was a slow process. The
system acquired a table lock before performing these checksum calculations, causing other
operations that required the lock to be blocked.
- New Behavior: Impala now collects file checksums and ACID
directory paths before acquiring the table lock. This change ensures that the time-consuming
process of fetching checksums does not block other operations. As a result, computing file
checksums during
INSERT operations with many files is now faster.Apache Jira: IMPALA-12162
