java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: for Hbase in Talend

Question

I have been trying to fetch the data from a Hbase table using HbaseInput component in Big data Batch.Like below.

I have not performed any transformation in the tMap, just trying to read the data from Hbase table.I have checked all the connections, they are connected fine. So, finally i built a job, copied it and ran in the cluster. The job gave me the below exceptions,

[WARN ]: org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper - Possibly transient ZooKeeper, quorum=zk:5181, exception=org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/hbaseid

Here is the table name,

It has written the row key, which i have hard coded in the component. And rest of the fields are empty. Yes, i have data in the table, it has millions of rows. I think talend is not able to fetch the data from my table, it is not communicating with it, as the exception says "Caused by: java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI:namespace1:table_name"

**Is this the right way to specify the table name?

Why am i not picking the data from the table?**

if i did not specify the namespace, it is throwing error similar to this. path /table_name does not exist.There are multiple areas where i should look.I will keep you posted — jack AKA karthik

sorry for the late reply, we have to specify the value like "namespace:table_name" if we do not enable "Set table namespace mappings". — jack AKA karthik

You are using MAPR distro, and it's a little bit different then other Hadoop distro.

In talend, you can go to advanced setting of the tHbaseInput component and set the following propetries :

hbase.table.namespace.mappings

or check the Set table Namspace mappings box and put your mapping to the table. See here.
