Subject Issue connectiong to HBase using Pig's HBaseStorage: Unable to find region for my_table
Date Mon, 20 Jan 2014 17:15:42 GMT
I'm having trouble connecting to HBase from Pig's
HBaseStorage<http://pig.apache.org/docs/r0.12.0/api/org/apache/pig/backend/hadoop/hbase/HBaseStorage.html>command.
Any help would be appreciated.

I'm running this command:

time_series = LOAD '/tmp/time_series.txt' AS (date_time:chararray,
time_series:chararray);

STORE time_series INTO 'hbase://bluecoat' USING
org.apache.pig.backend.hadoop.hbase.HBaseStorage('bytes_per_hour_time_series:series');


The output is thus:
