I have a hcatalog registered table to an hbase table and I am tryin to use Impala to query it
I get the following error when I try to query it
Backend 1:Decompressor: block size is too big. Data is likely corrupt. Size: 2564977884
Query is very simple but is trying to do a sort on the suffix portion of the key
select *
from stage.acct_txn_hbasetest
order by substr(key, locate('|',key,39)+1,14) desc
limit 25
;
hive resolves it in 300 sec
I figured Impala would be faster
Guess I have to try out SparkSQL
