> We are having serious data corruption issue when we are rolling restart of zookeeper
servers due to one application which is using ChildReaper recipe. I am not sure its root cause
but my theory is, when the multiple instances are running ChildReaper recipe, they would conflict
each other among checking exist and deleting paths. This conflict can cause data corruption.
We observed all servers died due to corrupted data and we had to manually copy log/snapshot
data and restart them.
