Arpit Agarwal updated HDFS-11339: --------------------------------- Component/s: (was: hdfs) datanode > Support File IO sampling for Datanode IO profiling hooks > -------------------------------------------------------- > > Key: HDFS-11339 > URL: https://issues.apache.org/jira/browse/HDFS-11339 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Reporter: Hanisha Koneru > Assignee: Hanisha Koneru > Fix For: 3.0.0-alpha2 > > Attachments: HDFS-11339.000.patch, HDFS-11339.001.patch, > HDFS-11339.002.patch, HDFS-11339.003.patch > > > HDFS-10958 introduces instrumentation hooks around DataNode disk IO and > HDFS-10959 adds support for profiling hooks to expose latency statistics. > Instead of profiling all the file IO events, we can sample a fraction of the > events and profile them. The fraction to be sampled can be configurable. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
