Subject Re: [REVIEW] Hadoop-1.1.0-RC4
Date Tue, 25 Sep 2012 01:59:21 GMT
Hi all,
Since the Review RC went out, I've been asked to include the following

Three significant bugs:
HDFS-3461 hftp uses http to the Namenode's https port, which doesn't work
HDFS-3846 NN deadlock
HDFS-3596 decrease the incidence of corrupted logs after disk full
and a related enhancement:
HDFS-3521 deal with edit log corruption if it occurs

Four unit test fixes (obviously not critical, but good to have):

and four performance enhancements:
HADOOP-8617, HDFS-496, MAPREDUCE-782 performance of CRCs calculations
HDFS-2751 Datanode drops OS cache behind reads even for short reads
MAPREDUCE-1906 default minimum heartbeat
MAPREDUCE-3289 use fadvise

I will spin a new RC with these fixes, and hope to offer it for vote by
