I was given a development cluster with 2 nodes, there're about 700 indexes there. I installed a plugin and it works very inconsistently. Sometimes it works normally, sometimes when I modify the code a bit, I can build and install the new code successfully but when I run query, it throws an error that "Native script [abc] not found". Then I modify the code and install again, it works again. Note again that there was no error every time I install the plugin. And of course I did restart elastic every time I install the plugin. Can anyone help pinpoint the possible reason for that behavior? Thanks a lot.
Btw I'm using Elasticsearch 1.7 and the cluster's health status is always yellow!
