---------------------------
Summary: Cannot query when cluster include more than 1 segment
Key: HAWQ-323
URL: https://issues.apache.org/jira/browse/HAWQ-323
Project: Apache HAWQ
Issue Type: Bug
Components: Core, Resource Manager
Reporter: zharui
Assignee: Lei Chang
The version I use is 2.0.0-beta-RC2. I can query data normally when cluster
hust have 1 segment. Once the cluster have more then 1 segments online, I
cannot finish any query and being informed that "ERROR: failed to acquire
resource from resource manager, 7 of 8 segments are unavailable (pquery.c:788)".
I have read the segment logs and the source code about resource manager. I
guess this issue is because of the communication failure between segment
instance and resource manager server. I can find the logs of the segment
connect to resource manager successfully such as "AsyncComm framework receives
message 518 from FD5" and "Resource enforcer increases memory quota to: total
memory quota=65536 MB, delta memory quota = 65536 MB", but the other online
segments have no these log.
