Re: Pig HBaseStorage error
I am wondering if my pig script is correct? I took it from some of the
examples from the wiki:

raw = LOAD 'hbase://SESSION_TIMELINE1'
       USING org.apache.pig.backend.hadoop.hbase.HBaseStorage(
       's_t_mtx:*', '-loadKey true -limit 5')
       AS (id:bytearray, s_t_mtx_map:map[]);
dump raw;
