Stack Overflow Asked on December 25, 2021
we have kafka cluster, version is 0.10
we can capture only the segment.bytes
value from zookeeper
we did the following approach
zookeeper-shell kafka1:2181 get /config/topics/topic_test
Connecting to kafka1:2181
WATCHER::
WatchedEvent state:SyncConnected type:None path:null
{"version":1,"config":{"segment.bytes":"10737555","retention.bytes":"104857600"}}
cZxid = 0xb30a00000038
ctime = Mon Jun 29 11:42:30 GMT 2020
mZxid = 0xb311000089d7
mtime = Fri Jul 24 08:04:38 GMT 2020
pZxid = 0xb30a00000038
cversion = 0
dataVersion = 9
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 81
numChildren = 0
we can see from above that also many details are printed from output
I want to know if we can run the zookeeper-shell in order to get only the "retention.bytes":"104857600"
details
maybe I am using the path of the topic instead other path ?
so the expected results should be
example
zookeeper-shell kafka1:2181 get /config/topics/topic_test
Connecting to kafka1:2181
WATCHER::
retention.bytes":"104857600
zookeeper-shell
cannot parse JSON. It only prints the binary data that is stored in the ZNodes
You will need to write parsing code around that command to extract that data
