Hi
I get an weird problem.
I try to create a core within Solr4.6.
Firstly, on my solr web server tomcat, a log come out[1]:
Then lots of Overseer Info logs come out as [2]. And then the creation
failed.
I have also notice that there is a lot of qn in the Overseer on the
zookeeper:
[zk: localhost:2181(CONNECTED) 45] ls /overseer/queue
[qn-0000000038, qn-0000000037, qn-0000000039, qn-0000000034, qn-0000000033,
qn-0000000036, qn-0000000044, qn-0000000035, qn-0000000042, qn-0000000043,
qn-0000000030, qn-0000000031, qn-0000000040, qn-0000000032, qn-0000000041]
Why are there so many qn.? I do not know the reason to the core creation
failed.
Please help .
