Hi,
We have a secured cluster. All components are working well, except hbase.
Specifically, this is what I see on regionserver:
2015-03-14 02:16:11,657 DEBUG [RpcServer.reader=5,port=60020]

In stand alone, you’re writing to local disk. You lose the disk you lose the
data, unless of course you’ve raided your drives.
Then when you lose the node, you lose the data because its not being
replicated. While this may not be a major issue or concern… you have to be
aware of it’s
Michael,
Thanks for your concern. Let me ask a few questions, since you’re implying
that HDFS is the only way to reduce risk and ensure security, which is not
the assumption under which I’ve been working.
A brief rundown of our problem’s characteristics, since I haven’t really
described what we’r
Meh.
Go to Hive instead.

Guys,
More than just needing some love.
No HDFS… means data at risk.
No HDFS… means that stand alone will have security issues.
Patient Data? HINT: HIPPA.
Please think your design through and if you go w HBase… you will want to build
out a small cluster.

HBase is telling you that writes to those datanodes are slow. Is it the
same host names over and over? Probably they have high system load, a bad
or dying disk, bad or dying network adapter, &c. Basically HBase is giving
you a hint to go diagnose your cluster.

Have you looked at the REST API? Can that be an option for you?

If you are comfortable with SQL
I would look into Phoenix

We usually try to have a shell way of doing all public facing operations.
In particular, I'd say if something shows up in the ref guide[1] without a
shell way to do it, I'd consider it a bug. The one big caveat is that the
shell is not performant for doing data inserts or fetching. Those functions
Hello:
If I am unable to do JAVA coding and prefer HBase shell for HBase
works/interactions, will I be able to do all operations?
i.e.
Is JAVA coding (Client API) needed to do something in HBase which is not
possible by HBase shell commands?
Thank You,

Hi, finally I met HBase perfomance problems :(
I see this message:
org.apache.hadoop.hbase.regionserver.wal.FSHLog
Slow sync cost: 345 ms, current pipeline: []
in log file
sometimes [] contains actual addresses of my datanodes.
What are the steps to undestand why HBase is so slow.
I have 7RS and
