Subject: [VOTE] Commit HDFS-927 to both 0.20 and 0.21 branch?
To: [EMAIL PROTECTED]
I'd like to open a vote on committing HDFS-927 to both hadoop branch
0.20 and to 0.21.
HDFS-927 "DFSInputStream retries too many times for new block
location" has an odd summary but in short, its a better HDFS-127
"DFSClient block read failures cause open DFSInputStream to become
unusable". HDFS-127 is an old, popular issue that refuses to die. We
voted on having it committed to the 0.20 branch not too long ago, see
only it broke TestFsck (See http://su.pr/1nylUn) so it was reverted.
High-level, HDFS-127/HDFS-927 is about fixing DFSClient so it a good
read cleans out the failures count (Previous failures 'stuck' though
there may have been hours of successful reads in betwixt). When
rolling hadoop 0.20.2 was proposed, a few fellas including myself
raised a lack of HDFS-127 as an obstacle.
HDFS-927 has been committed to TRUNK.
I'm +1 on committing to 0.20 and to 0.21 branches.
Thanks for taking the time to take a look into this issue.
