Re: zookeeper.znode.parent mismatch exception

Can you check if your ZK servers are actually forming a quorum or if they are just stand alone instances? If they don't form a quorum, znodes are just created on which ever zk server the master first connects to and the apps/RS connecting to other instances don't see the znode and thus raising this

No, we didn't upgraded. We are using HBase-0.94.1 The issue here is we are not always facing this issue, only once in a while we are facing this issue(2 or 3 times a day).Other times it working without any issue. Thanks,Sandeep. > Date: Thu, 12 Dec 2013 23:23:18 -0800 > Subject: Re: zookeeper.z

Re: zookeeper.znode.parent mismatch exception

Did you recently upgrade to 0.96? This is a problem I faced with mismatched clients connecting to an 0.96 cluster. Starting in that version, the root node for zookeeper chanced from /hbase to /hbase-unsecure (if in unsecure mode). On Thu, Dec 12, 2013 at 10:47 PM, Sandeep L wrote: > Hi, > Our pr

Re: HBase Client: How can I merge 2 results into 1?

I apologize, but I did a mistake. I was merging keyvalues from different rows (there was a problem in the way I was comparing and decoding the byte[] of rows) into a single result, which is not possible naturally. Therefore, I ask you to delete this thread. Thanks and sorry for any inconvenience.

HBase Client: How can I merge 2 results into 1?

Hi, I am using version 0.94.14 and I am trying to merge KeyValues of 2 results into 1 result. Basically somewhere in time I cache a keyvalue of a result: ### Putting in cache KeyValue with key: \x00\x09\x00\x00\x00\x04\x00\x00\x00\x00\x07\x011c\x00\x00\x01B\xE2\xE0\x0C\xEF\x04, tableName: STOCK,

Get all columns in a column family

I have use case where if one column of a column family changes, I would like to bring back all the columns in that column family. I can use the timestamp to identify the column that changes but it only returns the one column. Is there a way I can get all the columns of the column family back with o

Hi Suni, I'm not sure to get what you mean by "we want the clob/blob to go under _lobs directory". You want sqoop to get the blob field content, create a file under _lobs and put it's reference into _lob HBase column family? JM 2013/12/12 Suni K > Hi, > > I created a table with Blob Fields in
