Hi stack
Regarding the missing block part, my bad, i ddn't install this
cluster and didn't verify the ulimit first, then a new problem arose
because of the number of xceivers. Regarding this property, I can't
find the default value in hadoop-default.xml is this normal?
I think you'll find that not all configuration gets a mention in
hadoop-default.xml. If I were to guess, the developer is thinking that
"...no one will ever want to change this config. but just in case they
ever do and are dogged enough to read source....." HBase has a few of
these buried in source code.
I ask only because sometime ago you answered to someone to increase
the dfs.datanode.max.xcievers proeprty but actually the exceptions
refer to an *Xceiver (notice the change in the i,e order).
Oh. Bad. I can't spell (nor practise what the mnemonic says).
Anyway the problem seemed to go away so probably that fixed it.
Regarding the hang part the regionserver actually comes down (no
more jvm process), next time it happens I'll investigate further.
Please do. Check the .out file if you haven't in the past.
Good stuff,
