Thanks for the suggestions. I restarted the cluster again. Now things are fine.
I think the mistake I might have done earlier is that I did not restart HDFS nodes (name node + datanodes), but just the HBase nodes (master, zookeeper and region servers). Now, I restarted all, after cleaning the zookeeper data.
