Aaron T. Myers updated HDFS-5517: --------------------------------- Status: Patch Available (was: Open) > 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 > 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 (v6.1#6144)
