Hi,

I'm getting below errors in log file while starting datanode and
tasktracker. I'm using Hadoop 1.1.2 and java 1.7.0_21.

mmap failed for CEN and END part of zip file
mmap failed for CEN and END part of zip file
mmap failed for CEN and END part of zip file
mmap failed for CEN and END part of zip file
mmap failed for CEN and END part of zip file
mmap failed for CEN and END part of zip file

Please guide.

Thanks

Re: getting errors on datanode/tasktracker logs

Posted by Jitendra Yadav <je...@gmail.com>.
hi Jagat,

we have hdfs cluster in production running on java 1.6 without any
issue but on different Hadoop version.

I'm bit confused about this issue in our test env. Is this an issue
with java 1.7 version or Hadoop 1.1.2 version release?

Can you try with 1.6 java also.

With just starting daemons you are getting this error ?

I suppose this is your test cluster.
