Suresh Srinivas updated HDFS-1186: ---------------------------------- Fix Version/s: 0.20.205.0 > 0.20: DNs should interrupt writers at start of recovery > ------------------------------------------------------- > > Key: HDFS-1186 > URL: https://issues.apache.org/jira/browse/HDFS-1186 > Project: Hadoop HDFS > Issue Type: Bug > Components: data-node > Affects Versions: 0.20-append > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Priority: Blocker > Fix For: 0.20-append, 0.20.205.0 > > Attachments: HDFS-1186.20s.1.patch, HDFS-1186.20s.patch, hdfs-1186.txt > > > When block recovery starts (eg due to NN recovering lease) it needs to > interrupt any writers currently writing to those blocks. Otherwise, an old > writer (who hasn't realized he lost his lease) can continue to write+sync to > the blocks, and thus recovery ends up truncating data that has been sync()ed. -- This message is automatically generated by JIRA.
