Subject [jira] [Updated] (HDFS-1314) dfs.blocksize accepts only absolute value
Date Wed, 04 Jan 2012 17:14:39 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1314?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aaron T. Myers updated HDFS-1314:
---------------------------------

    Release Note: The default blocksize property 'dfs.blocksize' now accepts unit symbols
to be used instead of byte length. Values such as "10k", "128m", "1g" are now OK to provide
instead of just no. of bytes as was before.  (was: The default blocksize property 'dfs.blocksize'
now accepts size prefixes to be used instead of byte length. Values such as "10k", "128m",
"1g" are now OK to provide instead of just no. of bytes as was before.)

Amending the release note slightly since they're not really "prefixes."

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