Able to write files to an encryption zone but unable to read files from it

New Contributor

I was able to create an encryption zone on HDP and was able to write files into the zone using Talend ETL. However when I try to read files from the zone using the tool, I get the below error:

Exception in component tHDFSInput_1 No KeyProvider is configured, cannot access an encrypted file

at org.apache.hadoop.hdfs.DFSClient.decryptEncryptedDataEncryptionKey(

at org.apache.hadoop.hdfs.DFSClient.createWrappedInputStream(

at org.apache.hadoop.hdfs.DistributedFileSystem$4.doCall(

at org.apache.hadoop.hdfs.DistributedFileSystem$4.doCall(

at org.apache.hadoop.fs.FileSystemLinkResolver.resolve(


When I try to write and read files using the same Talend ETL user , using Hadoop dfs commands it works fine, implying the user has all the required permissions.

Please can some one guide me to the solution


Hi @PHANI TANGIRALA - do you have to provide configuration files to Talend in order to access your hadoop cluster? Can you check if the *-site.xml files have the following parameters configured correctly?

In core-site:

In hdfs-site:



@Ana Gillan

I am also facing the same issue. I have already specified above mentioned properties in talend but still it is not working. I am able to access the files from edge node cli using talend sudo user but not from talend.
