-----------------------------------------
Summary: Hadoop stack crash with LOGS TMUDF
Key: TRAFODION-2301
URL: https://issues.apache.org/jira/browse/TRAFODION-2301
Project: Apache Trafodion
Issue Type: Bug
Components: sql-general
Reporter: Roberta Marton
Assignee: Roberta Marton
There seems to be a problem is a that shows up when a tdm_udrsrvr process
takes most of the available Memory. When this happens, too much CPU time is
being used to handle this memory issue which causes some of Hadoop processes to
crash due to lack of resources. In addition, Linux is slow to respond from
the terminal.
It can be reproduced from DB Mgr using log page which calls UDR in the backend.
Calling this UDF (event_log_reader) from sqlci can also reproduce the problem.
When using sqlci, SQL prints out the udrserver process launched info but then
just hangs.
>>select [first 1]* from udf(event_log_reader());
