Subject Re: [jira] Commented: (PIG-17) Make Pig work with Hadoop 0.15
Date Tue, 20 Nov 2007 01:10:08 GMT
FYI, Hadoop 0.15.1 is about to be put out for a vote.  It contains 1  
incompatibility from Hadoop 0.15 to consider:

http://issues.apache.org/jira/browse/HADOOP-713

     HADOOP-713.  Reduce CPU usage on namenode while listing  
directories.
     FileSystem.listPaths does not return the size of the entire  
subtree.
     Introduced a new API ClientProtocol.getContentLength that  
returns the
     size of the subtree. (Dhruba Borthakur via dhruba)
