---------------------------------------
Summary: 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: Streaming
Reporter: Frederick Reiss
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 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.
