Shixiong Zhu updated SPARK-17475:
---------------------------------
Component/s: (was: DStreams)
Structured Streaming
> HDFSMetadataLog should not leak CRC files
> -----------------------------------------
>
> Key: SPARK-17475
> URL: https://issues.apache.org/jira/browse/SPARK-17475
> Project: Spark
> Issue Type: Sub-task
> Components: Structured Streaming
> Affects Versions: 2.0.1
> Reporter: Frederick Reiss
> Assignee: Frederick Reiss
> Fix For: 2.1.0
>
>
> When HDFSMetadataLog uses a log directory on a filesystem other than HDFS
> (i.e. NFS or the driver node's local filesystem), the class leaves orphan
> checksum (CRC) files in the log directory. The files have names that follow
> the pattern "..[long UUID hex string].tmp.crc". These files exist because
> HDFSMetaDataLog renames other temporary files without renaming the
> corresponding checksum files. There is one CRC file per batch, so the
> directory fills up quite quickly.
> I'm not certain, but this problem might also occur on certain versions of the
> HDFS APIs.
