> we have tow hdfs clusters with kerberos security, it means that mapreduce
> task need delegation tokens to authenticate namenode when hive on mapreduce
> run.
> Insert overwrite a table which location is on other cluster fail in kerberos
> cluster. For example,
> # yarn cluster's default fs is hdfs://cluster1
> # tb1's location is hdfs://cluster1/tb1
> # tb2's location is hdfs://cluster2/tb2
> # sql `INSERT OVERWRITE TABLE tb2 SELECT * from tb1` run on yarn cluster
> will fail
>
> reduce task error log:

> How to fix:
> After dig it, web found mapreduce job just obtain delegation tokens for input
> files in FileInputFormat. But Hive context get extendal scratchDir base on
> table's location, If the table 's location is on other cluster, the
> delegation token will not be obtained.
> So we need to obtaine delegation tokens for hive scratchDirs before hive
> submit mapreduce job.
