I see... did anything change with your configuration of HBase and
ZooKeeper on the MapR side of things?
The original stacktrace your provided is indicating the HBase client
is not authorized to access the /hbase znode in ZooKeeper.
If nothing changed on the MapR side of things, I have no idea way
Interestingly I didn't have to change nifi-hbase_1_1_2-client-service/pom.xml
to include mapr version of library in nifi 1.6 code.

Ravi,
The NullPointerException means that the Map-R version of the HBase
client (1.1.8-mapr-1703) is returning null for either
getClusterStatus() or getMaster().
Whatever version you were using before this was probably not returning
null. It would probably be a question to MapR as to why that ver
Hi Joe,
I am able to resolve this issue by changing hbase-client version to
1.1.8-mapr-1703 in the nifi-hbase_1_1_2-client-service/pom.xml.

Yes, if I change the version on hbase_client_service_1_1_2 to
nifi-hbase_1_1_2-client-service-nar-1.6.0-mapr.nar (nifi 1.6 code compiled with
mapr profile) it just connects fine.
If I change client service to
nifi-hbase_1_1_2-client-service-nar-1.7.1-mapr.nar (nifi 1.7.1 compiled with

it is very tough to read that stack trace as provided but the core
piece of it seems to be that authorization is failing for "/hbase".

present?
Thanks

Hi,
Until recently we were using nifi-1.6 nifi-hbase_1_1_2-client-service-nar
compiled with mapr profile. It has been working fine connecting to mapr
database without any issues.
Recently we are upgrading to nifi-1.7, hbase client service is failing to
connect with same mapr distribution.
