For the full list of fixed issues for all CDH components in CDH 5.16.2, see Issues Fixed in CDH 5.16.x. The following list represents the subset of fixed Impala JIRAs from the CDH fixed issues.

• IMPALA-6323 - Impala now supports a constant in the window specifications.
• IMPALA-7960 - Impala now returns a correct result when comparing TIMESTAMP to a string literal in a binary predicate where the TIMESTAMP is casted to VARCHAR of smaller length.

• IMPALA-8058 - Fixed cardinality estimates for HBase queries, which could sometimes yield hugely high numbers.
• IMPALA-8109 - Impala can now read the gzip files bigger than 2 GB.
• IMPALA-8212 - Fixed a race condition in the Kerberos authentication code.

For the full list of fixed issues for all CDH components in CDH 5.16.1, see Issues Fixed in CDH 5.16.x. The following list represents the subset of fixed Impala JIRAs from the CDH fixed issues.

• IMPALA-6086 - Require the SELECT privilege on the database for built-in function calls.
• IMPALA-6451 - Fixed the AuthorizationException in CTAS for Kudu tables.

For the full list of fixed issues for all CDH components in CDH 5.15.2, see Issues Fixed in CDH 5.15.x. The following list represents the subset of fixed Impala JIRAs from the CDH fixed issues.

• IMPALA-6907 - Now Impala correctly closes all stale connections to removed impala cluster members.
