[jira] [Created] (HIVE-25431) Enable CBO for null safe equality operator.
mahesh kumar behera created HIVE-25431: -- Summary: Enable CBO for null safe equality operator. Key: HIVE-25431 URL: https://issues.apache.org/jira/browse/HIVE-25431 Project: Hive Issue Type: Bug Components: Hive, HiveServer2 Reporter: mahesh kumar behera Assignee: mahesh kumar behera The CBO is disabled for null safe equality (<=>) operator. This is causing the sub optimal join execution for some queries. As null safe equality is supported by joins, the CBO can be enabled for it. There will be issues with join reordering as Hive does not support join reordering for null safe equality operator. But with CBO enabled the join plan will be better. -- This message was sent by Atlassian Jira (v8.3.4#803005)

[jira] [Created] (HIVE-25429) Delta metrics collection may cause number of tez counters to exceed tez.counters.max limit
Karen Coppage created HIVE-25429: Summary: Delta metrics collection may cause number of tez counters to exceed tez.counters.max limit Key: HIVE-25429 URL: https://issues.apache.org/jira/browse/HIVE-25429 Project: Hive Issue Type: Sub-task Components: Hive Affects Versions: 4.0.0 Reporter: Karen Coppage Assignee: Karen Coppage There's a limit to the number of tez counters allowed (tez.counters.max). Delta metrics collection (i.e. DeltaFileMetricsReporter) was creating 3 counters for each partition touched by a given query, which can result in a huge number of counters, which is unnecessary because we're only interested in n number of partitions with the most deltas. This change limits the number of counters created to hive.txn.acid.metrics.max.cache.size*3. Also when tez.counters.max is reached a LimitExceededException is thrown but isn't caught on the Hive side and causes the query to fail. We should catch this and skip delta metrics collection in this case. -- This message was sent by Atlassian Jira (v8.3.4#803005)
