Allen Wittenauer updated HDFS-6093: ----------------------------------- Labels: BB2015-05-TBR (was: ) > Expose more caching information for debugging by users > ------------------------------------------------------ > > Key: HDFS-6093 > URL: https://issues.apache.org/jira/browse/HDFS-6093 > Project: Hadoop HDFS > Issue Type: Improvement > Components: caching > Affects Versions: 2.4.0 > Reporter: Andrew Wang > Assignee: Andrew Wang > Labels: BB2015-05-TBR > Attachments: hdfs-6093-1.patch, hdfs-6093-2.patch, hdfs-6093-3.patch, > hdfs-6093-4.patch > > > When users submit a new cache directive, it's unclear if the NN has > recognized it and is actively trying to cache it, or if it's hung for some > other reason. It'd be nice to expose a "pending caching/uncaching" count the > same way we expose pending replication work. > It'd also be nice to display the aggregate cache capacity and usage in > dfsadmin -report, since we already have have it as a metric and expose it > per-DN in report output. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
