Subject Error with flush_length File in Orc, in hive 2.1.0 and mr execution engine.
Date Wed, 26 Oct 2016 00:46:04 GMT
HI All,

i am using hive 2.1.0 , hadoop 2.7.2 , but  when i try running queries like
simple insert,

set mapreduce.job.queuename=default;set
hive.exec.dynamic.partition=true;set
hive.exec.dynamic.partition.mode=nonstrict;set
hive.exec.max.dynamic.partitions.pernode=400;set

(pra.public_record_id is not null and TRIM(pra.public_record_id) <> '')
 then (case when (pra.primary_listing_id is null or
TRIM(pra.primary_listing_id) = '') then 'PR' else 'PRMLS' END)  else (case
when (pra.primary_listing_id is not null and TRIM(pra.primary_listing_id)

0,length(split(pra.url,'/')[0])-3) as city,
 substring(split(pra.url,'/')[0], length(split(pra.url,'/')[0])-1,2) as
state,  ml.mls_id  FROM access_logs.loadbalancer_accesslogs acl  inner join
mls_public_record_association_snapshot_orc pra on acl.listing_url = pra.url
 left outer join mls_listing_snapshot_orc ml on pra.primary_listing_id =
ml.id  left outer join attribute a on a.id = ml.standard_status  WHERE
acl.accesstimedate="2016-10-23";

i finally end up getting below error,

i also search for find the flush_length files in the above mentioned
location, but i only see buckets but no files ending with flush_length.

Any clue or help would be highly appreciated.

Satyajit.
