I'm attempting to write a Crunch pipeline to read various rows from a table in HBase and then do processing on these results. I am doing this from a cluster deployed using CDH 5.3.2 running Kerberos and YARN.
I was hoping to get an answer on what is considered the best approach to authenticate to HBase within MapReduce task execution context? I've perused various posts/documentation and it seems that TokenUtil was, at least at one point, the right approach, however I notice now it has been moved to be a part of the hbase-server package (instead of hbase-client). Is there a better way to retrieve and pass an HBase delegation token to the MR job launched by my pipeline? Thanks, Ed Skoviak
