Thomas Marquardt updated HADOOP-15446: -------------------------------------- Status: In Progress (was: Patch Available) Resuming progress with HADOOP-15446-002.patch > WASB: PageBlobInputStream.skip breaks HBASE replication > ------------------------------------------------------- > > Key: HADOOP-15446 > URL: https://issues.apache.org/jira/browse/HADOOP-15446 > Project: Hadoop Common > Issue Type: Bug > Components: fs/azure > Affects Versions: 3.0.2, 2.9.0 > Reporter: Thomas Marquardt > Assignee: Thomas Marquardt > Priority: Major > Attachments: HADOOP-15446-001.patch, HADOOP-15446-002.patch > > > Page Blobs are primarily used by HBASE. HBASE replication, which apparently > has not been used with WASB until recently, performs non-sequential reads on > log files using PageBlobInputStream. There are bugs in this stream > implementation which prevent skip and seek from working properly, and > eventually the stream state becomes corrupt and unusable. > I believe this bug affects all releases of WASB/HADOOP. It appears to be a > day-0 bug in PageBlobInputStream. There were similar bugs opened in the past > (HADOOP-15042) but the issue was not properly fixed, and no test coverage was > added. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
