RE: Distcp fails with "Got EOF but currentPos = 240377856 < filelength = 1026034162" error

2016-01-18 Thread Zheng, Kai 
Looks like a file it’s copying is ended unexpectedly. Maybe need to find out 
which file, check or read the file in other means to ensure it’s fine not being 
corrupt.

I'm using distcp with these options to copy a hdfs directory from one cluster 
to another:


hadoop distcp -prb -i -update -skipcrccheck -delete 
hftp://cluster1/user/hive/warehouse/dir1/ hdfs://cluster2/dir1/


I keep running into these errors related to EOF, what could be causing these 
errors and how to fix this:

Also I'm using the '-i' to ignore and continue on failures but the distcp does 
retry 3 times and stops. Can anyone throw some light on what else could be 
going wrong.


Thanks!

Thanks Kai, but I checked the parqet file that was reported to have issues
and fsck says the file is healthy.

Hi Buntu Dev,

Please check the Data node logs to get the exact root reason.
One more possible reason (apart from kai mentioned)can be direct buffer memory 
is not enough while copying the large files. If you observe the OOM in direct 
buffer, just increase it..

Hope it’s helpful.
