Re: HBase is able to connect to ZooKeeper but the connection closes immediately

Hi Marcos, Please fine the below code, this is working fine in pseudo distributed node but not in fully distributed cluster. We are using static for Configuration & HtablePool. * public static class ParsingMap extends MapReduceBase implements Mapper { public static HashMap mapHashMa

Re: HBase Client API: Why does HTable.get(get).getValue() return null if more than one family is added to the get instance?

Hi Desert, I try your code on 0.94.0, it works fine. Is there any detail you not list above or maybe there exist some JIRAs fixed this bug for 0.92.2? Can someone get this test run on 0.92.2 and give the result? Regards, NN 2012/6/11 Desert R. > > Sorry about my previous non-accurate descriptio

RE: hbase client security (cluster is secure)

Anyone have any direction for me on this matter? It's probably something simple that I'm doing wrong, but I can't figure it out. Thanks. -Original Message- From: Tony Dean Sent: Saturday, June 09, 2012 4:51 PM To: 'Harsh J'; user@hbase.apache.org Subject: RE: hbase client security (clu

RE: HBase Client API: Why does HTable.get(get).getValue() return null if more than one family is added to the get instance?

Sorry about my previous non-accurate description. Instead of 'family1' and 'family2' I used 'facebook_notify' (qualifier-less) and 'facebook' (with 2 qualifiers). After I read your post, I replaced the column 'facebook' by 'tweeter', a similar column that I have with 2 qualifiers also, and ever

I tried all three filters and got the same as below. HTTP ERROR 410 Problem accessing /tasklog. Reason: Failed to retrieve stderr log for task: attempt_201206101609_0001_m_98_0 I will try upgrading to the latest versions of both hadoop and hbase and see what happens too. If you have an

Hey Bryan, What value of scanner caching did you run this with? Could you try it with low values of 1-5? On Thu, May 31, 2012 at 9:57 PM, Bryan Keller wrote: > I have a large table that I am running a map reduce job on. The job scans for > a particular column value in the table using a TableInp

Re: DFS rebalance

Hey Eric, HDFS does not balance imbalanced DNs automatically. However DN imbalance is not something HDFS causes, its more to do with client write patterns. Ensure that your HDFS clients write from an edge node, not a DN node, else one block always gets written locally and that causes an imbalance.

Re: HBase Client API: Why does HTable.get(get).getValue() return null if more than one family is added to the get instance?

Hi, Am unable to reproduce this on 0.90.6 at least. What version are you using? Regardless of "get.addFamily(Bytes.toBytes("family2"));" being present or not, I do not receive a null. Original table scan (of a table 't'), to match your qualifier-less f1 family: x column=f1:, timestamp=133935

Re: Row Counter rpoblem

Hi Ryan, The issue doesn't seem to be ACLs if those are the only changed properties. I think the issue may be either this: "Error: Could not initialize class org.apache.log4j.LogManager" or better detailed at http://datanode003.cluster.local:50060/tasklog?plaintext=true&attemptid=attempt_20120610

The write process in the Region Server

Hi all, I'm trying to better understand what's going on in the region server during write to HBase. As I understand the process: 1. Data is written to memstore. 2. Once the memstore has reached hbase.hregion.memstore.flush.size -> memstore executes flush and writes a new StoreFile. 3. The number

HBase Client API: Why does HTable.get(get).getValue() return null if more than one family is added to the get instance?

Hi, I have a table with 2 column families. The column 'family1' has no qualifiers, and the row 'x' has the value \xFF. If I do the following HTable htable = new HTable(config, TABLE_NAME); Get get = new Get(Bytes.toBytes("x")); get.addFamily(Bytes.toBytes("family
