Hudson commented on HADOOP-15446: --------------------------------- SUCCESS: Integrated in Jenkins build Hadoop-trunk-Commit #14132 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/14132/]) HADOOP-15446. WASB: PageBlobInputStream.skip breaks HBASE replication. (stevel: rev 5b11b9fd413470e134ecdc7c50468f8c7b39fa50) * (edit) hadoop-tools/hadoop-azure/src/main/java/org/apache/hadoop/fs/azure/PageBlobInputStream.java * (add) hadoop-tools/hadoop-azure/src/test/java/org/apache/hadoop/fs/azure/ITestPageBlobInputStream.java > 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: 2.9.0, 3.0.2 > Reporter: Thomas Marquardt > Assignee: Thomas Marquardt > Priority: Major > Attachments: HADOOP-15446-001.patch, HADOOP-15446-002.patch, > HADOOP-15446-003.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
