> disable removing blocks to trash while rolling upgrade
> ------------------------------------------------------
>
> Key: HDFS-12348
> URL: https://issues.apache.org/jira/browse/HDFS-12348
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: datanode
> Reporter: Jiandan Yang
> Assignee: Jiandan Yang
> Attachments: HDFS-12348.001.patch, HDFS-12348.002.patch
>
>
> DataNode remove block file and meta file to trash while rolling upgrade，and
> do delete when
> executing finalize.
> This leads disk of datanode to be full, because
> (1) frequently creating and deleting files（eg，Hbase compaction);
> (2) cluster is very big, and rolling upgrade often last several days;
> Current our solution is clean trash by hand, but this is very dangerous in
> product environment.
> we think disable trash of datanode maybe a good method to avoid disk to be
> full.
