Subject [jira] [Commented] (HDFS-1314) dfs.block.size accepts only absolute value
Date Sat, 24 Dec 2011 16:40:31 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13175745#comment-13175745
] 

Harsh J commented on HDFS-1314:
-------------------------------

Sho,

FileSystem instance underneath for HDFS operations is DistributedFileSystem, so it should
be OK to use getDefaultBlockSize.

You even made the change in {{hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/DFSClient.java}}
that pertains to this. We should use it wherever is possible, and not repeat ourselves.

> Using "dfs.block.size=8mb" should throw some WARNING on NumberFormatException.
