Which elasticsearch version are you using?

This could happen if you don't have privileges on plugins dir.

Often, you have installed elasticsearch with a given account but you installed plugin using sudo which ends up creating a plugin dir not readable by elasticsearch user.

This NPE has been fixed in recent version. Wondering if it was not correctly fixed or if you are running an old version or if it's something else.

Also, this issue suddenly started coming up. We did installation yesterday,
indexed some data and were able to search it until this morning.

I see. This fix has not been added in 1.0 branch but in 1.x: https://github.com/elasticsearch/elasticsearch/issues/5195

Could you check subdirs?
I think you have an issue with your directories.

No. I have no idea.
I think something is wrong with your installation.

Could you just

download elasticsearch 1.0.1 (zip or tar.gz file)
unzip it
Run bin/plugin -install xxxxx (your plugin)
Run bin/elasticsearch

Only those commands please.

If it works, then something went wrong when you installed your elasticsearch version.
Could you describe how you installed elasticsearch?

Finally got this working. Our Java application that communicates with
elasticsearch is hosted in JBoss server. While creating the transport
client we were not passing elasticsearch home dir, plugin dir path
explicitly. The default path that was picked up had some wrong reference.
We managed to resolve the issue after passing the correct value to
path.home.

No. I have no idea.
I think something is wrong with your installation.

Could you just

download elasticsearch 1.0.1 (zip or tar.gz file)
unzip it
Run bin/plugin -install xxxxx (your plugin)
Run bin/elasticsearch

Only those commands please.

If it works, then something went wrong when you installed your
elasticsearch version.
Could you describe how you installed elasticsearch?

I see. This fix has not been added in 1.0 branch but in 1.x:
NPE in PluginsService when starting elasticsearch with a wrong user · Issue #5195 · elastic/elasticsearch · GitHub

Could you check subdirs?
I think you have an issue with your directories.

Which elasticsearch version are you using?

This could happen if you don't have privileges on plugins dir.
Often, you have installed elasticsearch with a given account but you
installed plugin using sudo which ends up creating a plugin dir not
readable by elasticsearch user.

This NPE has been fixed in recent version. Wondering if it was not
correctly fixed or if you are running an old version or if it's something
else.

We are unable to perform any action on elasticsearch.

Any idea what could be the issue?
