Hi
I have set up cluster. I am using external zookeeper. I have the same
connection strings in nifi.properties and state-management.xml files.
DistributedMapCacheServer is set up under controller services. One
interesting think I noticed that there is not any record under
Referencing Components under DistributedMapCacheServer settings tab but
I have set Distributed Cache Service property under ListHDFS processor.
I can get ListHDFS processor record from zookeeper cluster:
[zk: localhost:2181(CONNECTED) 1] get
/nifi/components/cb084e86-0159-1000-0000-00001b125b80
1484732837694listing.timestamp
cZxid = 0x800000315
ctime = Mon Jan 23 13:20:48 EET 2017
mZxid = 0x8000022cf
mtime = Mon Jan 23 14:55:47 EET 2017
pZxid = 0x800000315
cversion = 0
dataVersion = 7091
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 77
numChildren = 0
[zk: localhost:2181(CONNECTED) 2]
but trying to get state via NIFI I will get:
Unable to get the state for the specified component
cb084e86-0159-1000-0000-00001b125b80: java.io.IOException: Failed to
obtain value from ZooKeeper for component with ID
cb084e86-0159-1000-0000-00001b125b80 with exception code CONNECTIONLOSS
any hint?
