Subject OutOfOrderScannerNextException with phoenix 4.6-HBase-1.0-cdh5.5
Date Wed, 10 Feb 2016 18:36:59 GMT
I'm getting below exception in SELECT DISTINCT query using tenant-specific
connection  with phoenix 4.6-HBase-1.0-cdh5.5 .

The exception disappears if I either switch to non-tenant connection, or
remove DISTINCT from the query.

Caused by: *org.apache.hadoop.hbase.exceptions.OutOfOrderScannerNextException*:
*org.apache.hadoop.hbase.exceptions.OutOfOrderScannerNextException*:
Expected nextCallSeq: 1 But the nextCallSeq got from client: 0;
request=scanner_id: 2326 number_of_rows: 100 close_scanner: false
next_call_seq: 0 client_handles_partials: true
client_handles_heartbeats: true


I'm using phoenix 4.6 for cloudera cdh5.5.1 community edition
