Fixed Issues in Kudu

Review the list of Kudu issues that are resolved in Cloudera Runtime 7.3.1, its service packs and cumulative hotfixes.

Cloudera Runtime 7.3.1.400 SP2:

CDPD-82273: Backport KUDU-3661 Ranger policy not honored in Kudu
Fixed an issue in the Ranger authorization provider that could cause some table privileges to be missing in certain environments. This happened when processing the SELECT privilege, which caused the system to stop checking for additional permissions. The issue was primarily seen on RHEL/CentOS 8 systems due to platform-specific behavior in the underlying system libraries.
CDPD-82275: Run a range-aware cluster rebalance with multiple tables
Previously, when rebalancing a cluster with the Kudu command-line tool, the --enable_range_rebalancing flag required the --tables flag to specify exactly one table. This fix removes that restriction. You can now pass multiple tables to the --tables flag when range rebalancing is enabled. Range-partitioned tables among those specified will be rebalanced with ranges considered, while other tables rebalance as usual. If you do not set the --tables flag, all tables in the cluster will be rebalanced.
CDPD-81231: Backport KUDU-3638, disable KUDU-3486 behavior by default
This fix addresses an issue with tombstoned tablets caused by functionality introduced in KUDU-3486. The fix disables this functionality. To re-enable the behavior, adjust the --tserver_send_tombstoned_tablets_report_interval_secs flag as needed.
CDPD-81229: Backport KUDU-3647 more robust zlib wrapper code
This fix improves robust error handling for the utility wrappers zlib::{CompressLevel, Uncompress}(). It also resolves a data corruption issue in Base64Decode(), where trailing bytes encoded as 'A' were previously discarded.
CDPD-81234: Backport KUDU CVE fixes
This fix addresses recently identified security vulnerabilities. The following third-party components have been upgraded:
  • protobuf: Upgraded to address CVE-2022-3171.
  • zlib: Upgraded to address CVE-2022-37434.
  • curl: Upgraded to address CVE-2024-11053.

Resolved a long-standing bug by fixing a race condition within the OpDriver. This fix improves stability and ensures the expected behavior of the driver.

CDPD-78316: Disable KUDU-3367 behavior by default
This fix addresses an issue with major delta compaction caused by functionality introduced in KUDU-3367. The fix disables the functionality by adjusting the default value of the -all_delete_op_delta_file_cnt_for_compaction flag. While the original functionality was intended to optimize Kudu deployments of early versions, the functionality introduced by KUDU-3367 isn't relevant for data generated by Kudu servers in Cloudera Base on premises 7.1.1 and newer versions.

Apache Jira: KUDU-3619.

Cloudera Runtime 7.3.1

KUDU-3576: Fix the Connection timeout After Tablet Server Restart
7.3.1

In Kudu, if a Java client application maintains an open connection to a tablet server and the tablet server is restarted or encounters a network error, the client cannot re-establish communication with the tablet server even after it comes back online. The fix resolves the issue by updating the Kudu Java client.

KUDU-3447: Limit the usage of network bandwidth of tablet copying
7.3.1
Two new flags are introduced in Kudu CLI tools to copy tablets kudu tablet copy_from_remote command to limit the speed of the copy task and avoid resource contention.

Apache Jira: KUDU-3447

KUDU-3353: Add an immutable attribute to column schema

Apache Jira: KUDU-3351

KUDU-3526: Scanner should bound with a tserver in java client
7.3.1
The scanner in the Kudu Java client now binds with the Kudu tablet server. This prevents scanning failures that occur when scanning from the leader replica and leadership changes to a different replica.
