Hi,
I have a node which is unable to connect to other nodes of the cluster
(probably because they are running out of file descriptors).
I try to shutdown that node with
service elasticsearch stop
- Stopping Elasticsearch Server
...done.
But I can still see the process if I do:
ps aux | grep elast
And actually in the ElasticSearch log there is no log line related to the
shutdown.
I can wait several minutes, but still the process stays there.
If I kill it, either with SIGTERM or SIGKILL and then I try to run ES
again, I get:
/usr/share/elasticsearch/bin/elasticsearch -p /var/run/elasticsearch.pid
--default.config=/etc/elasticsearch/elasticsearch.yml
--default.path.home=/usr/share/elasticsearch
--default.path.log/var/log/elasticsearch
--default.path.data=/var/lib/elasticsearch
--default.path.work=/tmp/elasticsearch
--default.path.conf=/etc/elasticsearch -Des.max-open-files=true
log4j:WARN No such property [datePattern] in
org.apache.log4j.RollingFileAppender.
log4j:ERROR Could not find value for key
log4j.appender.index_indexing_slow_log_file
log4j:ERROR Could not instantiate appender named
"index_indexing_slow_log_file".
log4j:ERROR Could not find value for key
log4j.appender.index_search_slow_log_file
log4j:ERROR Could not instantiate appender named
"index_search_slow_log_file".
and the process stucks there.
If I reboot the instance I arrive to the same point. I have to terminate
that instance and create a new one, reinstalling ES.
It is ES 1.4.4 on Ubuntu 14.04 amd64 kernel 3.13.0-44-generic.
For me it seems like ES in a loop trying to discover a master, and it is
unresponsive to anything else. I didn't try to shut it down via the
Shutdown API.
Thanks for any help.
