> The problem is ‘hadoop fs’ calls. One call takes 3-30 seconds depending on
> node load CPU/RAM etc. Mostly this is because every time call is done new jvm
> is created and probably due to some DN/NN communication is redone. Since we
> have more and more this calls triggered with every release, this became a
> problem now.
> *BASIC SOLUTION DESCRIPTION*
> Instead of copying files to hdfs and creating directories one by one, by
> calling countless number of ‘hadoop fs’ calls, we can do one single execution
> of the jar file which will do all the creating it is asked.
> For example:
> {noformat}
> hadoop -fs -mkdir /a
> hadoop -fs -chmod 755 /a
> hadoop -fs -chown ambari-qa /b
> hadoop -fs -copyFromLocal /x /y
> {noformat}
> Can be replaced with
> resources.json like this which is passed to our new jar (below):
> {noformat}
> {
> {
> “path”:”/a”
> “type”: directory”
> “mode”: “755”
> },
> {
> “path”:”/b”
> “type”: directory”
> “owner”: “ambari-qa”
> },
> {
> “path”:”/y”
> “type”: directory”
> “source”: “/x”
> },
> }
> {noformat}
> which will handle all that only in one single time-expensive call:
> *hadoop jar create-hdfs-resources.jar resources.json*
> For synchronization between nodes (to know who and when executes this time
> expensive calls) ZK is used for more details please read the doc below
