Unexpected end of input stream

Hi

I have a lot of compressed gzip files on hdfs.
An exception has occurred at TaskTracker, during processing of MR.
If any file is invalid, may I know that?

Hi,

I had same error few days back.

Now difficulty we have is to find which gz file is corrupt. Its not corrupt
as such but some how hadoop says it is. If you made the file in Windows and
then transfer to hadoop of can give. This error. If you want to see which
file is corrupt do select count query and watch job tracker for error , it
would give name of gz file currently processed and then of it fails you can
find and remove that file. You can then again gzip that in some Linux
machine and upload it would work.

Thanks,

Hi Kiwon

You can get this information from the jobdetails web page itself. Browse to your failed task and there you can see the details on which file/block it had processed and failed with the error.

That basically means your data was not in the correct format when you move
or copied the data to HDFS. So there is one file which is corrupted, you
can find the file name in your error logs.
