HBase Error : zookeeper.znode.parent mismatch

The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

If you come across this error, while starting Hbase, then, check Hbase-Site.XML file (For me it was in /usr/lib/hbase-0.96.2-hadoop2/conf folder).

Check if Znode is present else add this property to existing XML node.

<configuration>
        <property>
                <name>zookeeper.znode.parent</name>
                <value>/hbase-unsecure</value>
        </property>
</configuration>

This is done for Stand-Alone mode. I am not sure how it is done for clusters.

Zip/Unzip multiple files and also include password for zipped file using SSIS

We have many scenario that we need to Zip many files which we come across and then so some operations like either sending it as a email or just moving zipped file to some other destinations etc. But we were using manual method to zip multiple files. In this post, I tried to create a package which will zip multiple files using SSIS. Here for Zipping files purpose, I'm using 7-ZIP which is free software available in google sites. Download files and install onto your system. First let me show how to Zip on file and later I will show how to zip multiple files using SSIS and 7Zip tool. Compressing Single file. Here I'm trying to Zip one single flat file which is of 40MB size. I kept this file in C:\Documents and Settings\\Desktop\test\source folder. Now to compress this file, I will open my SSIS and I'm dragging and dropping EXECUTE PROCESS TASK from Control Flow. Now right click on Execute Process task and go for edit and select Process option. In process tab,

SSIS: The Value Was Too Large To Fit In The Output Column

I had a SSIS package where I was calling a stored procedure in OLEDB Source and it was returning a “The Value Was Too Large to Fit in the Output Column” error. Well, My Datatype in OLEDB source was matching with my OLEDB Destination table. However, when I googled, we got solutions like to increase the output of OLEDB Source using Advanced Editor option . I was not at all comfortable with their solution as my source, destination and my intermediate transformation all are having same length and data type and I don’t want to change. Then I found that I was missing SET NOCOUNT ON option was missing in Stored Procedure. Once I added it, my data flow task ran successfully. 

How to move multiple files in ssis and also rename simultaneously

There are two ways to achieve this. 1) We can move the flat files and then rename it. 2) While moving files itself, automatic rename should be done. We will do the second type. The criteria is to rename the files while moving from source to destination. So for that, we need FILE SYSTEM TASK to be included. Secondly since we need to move many files, we will use FOR EACH LOOP CONTAINER. To fetch all the files, we can use FOR EACH LOOP task in SSIS. In collection tab, we can select FOREACH FILE enumerator option for fetching files and we can change enumerator configuration Folder option: Points to source where we need to fetch files. Files: will give us idea whether we need to fetch all the files (*.*) or if we give extension like *.txt, it is going to fetch only  .txt files . Once I give Source name in FOR EACH LOOP container, It is going to fetch all the files corresponding to that path. Retrieve file name: This option is used to let the variables mentioned in VARIA
