Thanks for your response Azuryy.

These fiels are under the same directory, different files.
My input path is configured using oozie throughout the propertie

Hi All,
I am also looking into migrating\upgrading from Apache Hadoop 1.x to Apache
Hadoop 2.x.
I didn’t find any doc\guide\blogs for the same.
Although there are guides\docs for the CDH and HDP migration\upgradation from
Hadoop 1.x to Hadoop 2.x
Would referring those be of some use?
I am
For MapReduce and YARN, we recently published a couple blog posts on

One more thing,
if we split the files then all the records are processed. Files are of 70,5MB.

I do think this is because of your RecorderReader, can you paste your code
here? and give a piece of data example.
please use pastebin if you want.

It would be nice if HADOOP_CONF_DIR could be set in the environment like
YARN_CONF_DIR. This could be done in lib-exec\hadoop_config.cmd by setting
HADOOP_CONF_DIR conditionally.

There is problem in the 'initialize', generally, we cannot think
split.start as the real start, because FileSplit cannot split on the end of
the line accurately, so you need to adjust the start in the 'initialize'
to the start of one line if start is not equal to '0'.
also, end = start +
