Steve Loughran commented on SLIDER-876:
---------------------------------------
This is interesting, looks like >1 problem is arising.
1. the unicode message looks related to
[this|http://stackoverflow.com/questions/24475393/unicodedecodeerror-ascii-codec-cant-decode-byte-0xc3-in-position-23-ordinal];
it implies that something isn't working with the slider.py script on your
system.
can you do an {{echo $LANG}} to tell us what language your system thinks it is?
2. The last Log4J report was zookeeper-related; it says it was trying to
reconnect but failing. I wonder if something is up with ZK.
If you try this again and it hangs, can you do a {{kill -QUIT}} against the
slider process (which {{jps -v}} will help you find), so we can get a stack
trace of where the client is hanging.
3. Finally, if you look at [our exit codes
doc|http://slider.incubator.apache.org/docs/exitcodes.html] you can see our
list of errors. #73 is "application in use". Have a look at the YARN Resource
manager web UI —is it still listed as running?
