Hey all, I'm just getting started with Hive, and am trying to follow the instructions on https://cwiki.apache.org/confluence/display/Hive/HBaseBulkLoad. I can create my table fine, but when I run
insert overwrite table hb3 select key, val from hb2 cluster by key; the map phase runs fine, but the reduce fails with the attached error message. I found a thread suggesting that I "add jar hive-contrib-VERSION.jar;" this didn't seem to fix it. I'm using 0.7.1-cdh3u1. Does anyone know what might be causing this? Thanks! -Ben java.lang.RuntimeException: Error in configuring object at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:93) at
