Also manifests as “Instance Id does not exist in Zookeeper”.
I was trying to set up a standalone instance of Hadoop + Zookeeper + Accumulo yesterday and found that after every reboot I needed to destroy and recreate my Accumulo instance, otherwise it wouldn’t connect to Zookeeper. It didn’t seem to make a difference whether I did a clean shutdown or not.
Turns out I didn’t read zoo.cfg very carefully:
# the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=/tmp
Make sure that your Zookeeper data is being saved in a spot where it won’t get blown away on every reboot!
