Flink Jira Bot updated FLINK-11695:
-----------------------------------
Labels: auto-unassigned stale-major (was: auto-unassigned)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.

> Key: FLINK-11695
> URL: https://issues.apache.org/jira/browse/FLINK-11695
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing
> Reporter: Yun Tang
> Priority: Major
> Labels: auto-unassigned, stale-major
>
> We meet this annoying problem many times when the {{sharedStateDir}} in
> checkpoint path exceeded the directory items limit due to large checkpoint:
> {code:java}
> org.apache.hadoop.hdfs.protocol.FSLimitException$MaxDirectoryItemsExceededException:
> The directory item limit of xxx is exceeded: limit=1048576 items=1048576
> {code}
> Currently, our solution is to let {{FsCheckpointStorage}} could create
> sub-dirs when calling {{resolveCheckpointStorageLocation}}. The default value
> for the number of sub-dirs is zero, just keep backward compatibility as
> current situation. The created sub-dirs have the name as integer value of
> [{{0, num-of-sub-dirs}})
