Hi all:Recently, I updated my hadoop cluster from hadoop-2.0.0-cdh4.3.0 to
hadoop-2.5.0-cdh5.2.0. It works fine, however, a small problem is, when i use
the hadoop fs -ls command in the terminal to get the list of files in the hdfs,
it took much more time(10+ sec) to get the response compared to 2-3 secs before
i update the version of hadoop.( get is slow too)Can any one exaplain a little
bit of what might cause the problem or some configuration goes wrong?Below is
the log:
