Ted Yu commented on HBASE-5712: ------------------------------- The new sentence is better. +1. > Parallelize load of .regioninfo files in diagnostic/repair portion of hbck. > --------------------------------------------------------------------------- > > Key: HBASE-5712 > URL: https://issues.apache.org/jira/browse/HBASE-5712 > Project: HBase > Issue Type: Sub-task > Components: hbck > Affects Versions: 0.90.7, 0.92.2, 0.94.0, 0.96.0 > Reporter: Jonathan Hsieh > Assignee: Jonathan Hsieh > Attachments: hbase-5712-90.patch, hbase-5712.patch > > > On heavily loaded hdfs's some dfs nodes may not respond quickly and backs off > for 60s before attempting to read data from another datanode. Portions of > the information gathered from hdfs (.regioninfo files) are loaded serially. > With HBase with clusters with 100's, or 1000's, or 10000's regions > encountering these 60s delay blocks progress and can be very painful. > There is already some parallelization of portions of the hdfs information > load operations and the goal here is move the reading of .regioninfos into > the parallelized sections.. -- This message is automatically generated by JIRA.
