Andrew Wang updated HDFS-5517: ------------------------------ Target Version/s: 3.0.0-alpha2 (was: 2.8.0) > Lower the default maximum number of blocks per file > --------------------------------------------------- > > Key: HDFS-5517 > URL: https://issues.apache.org/jira/browse/HDFS-5517 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 2.2.0 > Reporter: Aaron T. Myers > Assignee: Aaron T. Myers > Labels: BB2015-05-TBR > Attachments: HDFS-5517.patch > > > We introduced the maximum number of blocks per file in HDFS-4305, but we set > the default to 1MM. In practice this limit is so high as to never be hit, > whereas we know that an individual file with 10s of thousands of blocks can > cause problems. We should lower the default value, in my opinion to 10k. -- 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
