Hi, we are testing ELK 6.6.1 on s390x platform (Linux on Z).
We have 3 elasticsearch nodes configured as:
client:
discovery.zen.ping.unicast.hosts: master-discovery
discovery.zen.minimum_master_nodes: 1
node.master: false
node.data: false
http.enabled: true
http.port: 9200
data:
discovery.zen.ping.unicast.hosts: master-discovery
discovery.zen.minimum_master_nodes: 1
node.master: false
node.data: true
http.enabled: false
master:
discovery.zen.ping.unicast.hosts: master-discovery
discovery.zen.minimum_master_nodes: 1
node.master: true
node.data: false
http.enabled: false
After starting the ELK 6.6.1 stack, everything seems fine and we can see logs on Kibana UI, but elasticsearch client node's log is flooded with the entries like below:
[2019-07-07T12:39:53,698][WARN ][o.e.d.c.u.ByteSizeValue ] [logging-elk-client-54595cd8c-rfw5s]Values less than -1 bytes are deprecated and will not be supported in the next major version: [-5938528256b]
[2019-07-07T12:39:55,254][WARN ][o.e.d.c.u.ByteSizeValue ] [logging-elk-client-54595cd8c-rfw5s]Values less than -1 bytes are deprecated and will not be supported in the next major version: [-5915230208b]
...
Any idea what's going on there?
We took a javacore and reviewed all the classes loaded to the JVM, but could not find the exact class "o.e.d.c.u.ByteSizeValue". There is only one ByteSizeValue class:
3CLTEXTCLASS org/elasticsearch/common/unit/ByteSizeValue(0x000000000033AE00)
If I understood correctly, this one's short name should be o.e.c.u.ByteSizeValue (not the o.e.d.c.u.ByteSizeValue).
Best regards.
