Hi,
I am trying to get the HBaseReadExample to run. I have filled a table with the
HBaseWriteExample and purposely split it over 3 regions.
Now when I try to read from it the first split seems to be scanned (170 rows)
fine and after that the Connections of Zookeeper and RCP are suddenly closed
down.
Does anyone has an idea why this is happening?
Best regards,
Lydia
