Re: File split query

Hadoop will take care of it. If the split is supposed to be at the middle of
the
line, then it will be extended till the end. Though the split limit will be
exceeded
by few bytes.

 Hi,
   When framework splits a file, will it happen that some part of a
 line falls in one split and the other part in some other split? Or is
 the framework going to take care that it always splits at the end of
 the line?

 Thanks,
 Udaya.

Hi Santosh,

Check whether all the datanodes are up and running, using
the command
'bin/hadoop dfsadmin -report'.
