RegionObserver issue: ZooKeeperServer: Refusing session request as it
has seen zxid 0x38 our last zxid is 0x30 client must try another server
Hi there,
Thanks for the help i have got from this HBASE group.
Here is a new question: I was trying to implement a region observer
which creates/updates a row if it detects some operation for a table.
But the region observer stopped at some point and the log shows:
"ZooKeeperServer: Refusing session request for client
/0:0:0:0:0:0:0:1%0:56366 as it has seen zxid 0x38 our last zxid is
0x30 client must try another server"
I am not sure what this means and how to solve that. I also don't know
if a region observer can write something to another region on anther
region observer.
Thanks for the help.
Best,
James
