Known Issues in Cloudera Runtime 7.3.1
- Kudu supports both coarse-grain and fine-grain authorization,
but Kudu does not yet support integration with Atlas.
- None
- KUDU-3619: Major delta compaction for a tablet might fail for
particular workloads due to a bug introduced with KUDU-3367
- 7.3.1.100
- 7.3.1
- A bug has been introduced with KUDU-3367 functionality. The bug
manifests itself when a tablet server's maintenance thread attempts to run a major delta
compaction on a tablet where many rows have been deleted, and the attempt fails with an
error. To know more about the error message pattern, see KUDU-3619. If that happens, the
corresponding tablet might accumulate a lot of updates that cannot be compacted and
later garbage collected. In extreme cases, it could lead to running out of disk space
when many tablet replicas hosted at the same tablet server hit the issue.
- If a tablet server is affected by the issue, messages like the
below are present in the tablet server's logs, where <tabletUUID> and <rowsetID>
placeholders are populated with corresponding identifiers:
- Major delta compaction failed on <tabletUUID>: Corruption:
Failed major delta compaction on RowSet(<rowsetID>): No min key found: CFile base
data in RowSet(<rowsetID>).
- Set the
--all_delete_op_delta_file_cnt_for_compaction flag to a very high
value (e.g. 1000000) using the Tablet Server Advanced Configuration Snippet
(Safety Valve) for gflagfile in the Cloudera Manager UI and restart all the tablet servers in the Kudu
cluster.Apache Jira:
KUDU-3619.
