When you install pymssql module using pip in python and then try to import pymssql, you may end up with “ PyMSSql - import _mssql - ImportError: DLL load failed: The specific module could not be found ” error, if you are using pymssql version 2.1 or greater. This is due to security reason, pymssql now is not linked with SSL and FreeTDS, unlike previous version where SSL and FreeTDS were jointly linked with pymssql during installation. This information can be found on pymssql site found http://pymssql.org/en/latest/freetds.html#windows In order to overcome, we need to install supporting components FreeTDS and OpenSSL independently and then pymssql will work without any issue. Below are the steps to download and configure FreeTDS and OpenSSL. FreeTDS can be downloaded https://github.com/ramiro/freetds/releases And extract the file which is download. Now place the extract folder where your python module is installed.  (Can be kept anywhere but to avoid accide...

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.

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.
