PXF Cluster STOP - Segmentation fault

[Jacques Blaauw]

Good day,

I'm trying to stop PXF on my Master Host, but am getting the error below.

I came across the following thread: https://github.com/greenplum-db/pxf/issues/637

but that does not seem to be the issue on mu case (see variables below).

[gpadmin@abc03 ~]$ pxf version
PXF version 5.15.1
[gpadmin@ abc03   ~]$ pxf cluster stop
Segmentation fault
[gpadmin@ abc03   ~]$ echo $PXF_HOME
/usr/local/pxf-gp6
[gpadmin@ abc03   ~]$ echo $PXF_CONF
/usr/local/pxf-conf

Any help on how to resolve this issue please?

Thank you!

Hi Jacques,

We had some reports (e.g. the issue you're referring to) of this error, but the root cause is unknown. Collocation of PXF_HOME and PXF_CONF seemed to be one of the potential reasons.

You can try a few things:
- check $PXF_HOME/conf/pxf-env-default.sh and see what PXF_CONF was set to in "export PXF_CONF=" line

- check directly on the segment hosts whether non-cluster commands still work: "pxf init", "pxf start", "pxf stop"

If the commands on the segment hosts work and only cluster commands fail, as a workaround, you can orchestrate cluster management yourself via custom scripts (connect to each segment host and perform the operation).

But in general, PXF5 is several years old and does not receive any new features. We advise to switch to PXF6, if possible.
