Subject [jira] Updated: (HBASE-1948) updates to existing tables do not get reflected after a complete HBase + Hadoop + Zookeeper restart
Date Mon, 02 Nov 2009 18:30:59 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1948?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gautam Sampathkumar updated HBASE-1948:
---------------------------------------


Hi Stack,
          I think this problem is seen regardless of the size of the table, but I have a table
that's 'column-heavy'. I have 2 rows and about 10K+ columns per row. Database size is about
25MB.

No instance of HBase region server is started up because I have hbase.cluster.distributed
set to false. I have Hbase set to manage my Zookeeper instance.

I believe that the problem may be related to the fact that hadoop's namenode may rearrange
block information when it starts up and this is not reflected in hbase which still attempts
to use old locations.

I hope that helps. Please let me know if you need more information. I will attach my hdfs-site.xml
and hbase-site.xml. Since this is my test/dev environment the settings are pretty minimal

>          Issue Type: Bug
>          Components: client
>    Affects Versions: 0.20.1
>         Environment: ubuntu 9.04
> hadoop 0.20.1 (single machine mode)
> hbase 0.20.0 (pseudo-distributed mode i.e. using HDFS on a single machine)
> zookeeper 3.2.1

> I have an existing hbase table with data in it. When I restart hadoop, hbase and zookeeper,
I am able to read all of the data that existed in the table prior to the restart. However
when I write data to the table, it does not get reflected. 
> When I do a disable <table> and then an enable <table> on an hbase shell.
The data that was written to the table now appears and the table is up to date. However, even
after this my thrift client still sees the old data and not the updated values.
