I've been struggling to do a basic upconfig both with embedded and actual Zookeeper in Solr 7.2.1 using the zkcli script on OSX.
One variable, I recently upgraded to Java 9. I get slightly different errors on Java 8 vs 9 This is probably me being dumb, but googling / searching Jira hasn't really yielded anything fruitful. Perhaps my google fu is weak this morning. Thanks for any help -Doug Java 9: doug@wiz$~/ws/foo(mas) $ /Users/doug/bin/solr-7.2.1/server/scripts/cloud-scripts/zkcli.sh -zkhost localhost:2181 -cmd upconfig -confdir solr_home/foo/ -confname foo_conf WARN - 2018-04-04 09:05:28.194; org.apache.zookeeper.ClientCnxn$SendThread; Session 0x100244e8ffb0004 for server localhost/127.0.0.1:2181, unexpected error, closing socket connection and attempting reconnect java.io.IOException: Connection reset by peer at java.base/sun.nio.ch.FileDispatcherImpl.read0(Native Method) at java.base/sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:39) at java.base/sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:223) at java.base/sun.nio.ch.IOUtil.read(IOUtil.java:192) at java.base/sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:382) at org.apache.zookeeper.ClientCnxnSocketNIO.doIO(ClientCnxnSocketNIO.java:68) at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:366) at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1141) WARN - 2018-04-04 09:05:28.310; org.apache.solr.common.cloud.ConnectionManager; Watcher org.apache.solr.common.cloud.ConnectionManager@3eed2369 name: ZooKeeperConnection Watcher:localhost:2181 got event WatchedEvent state:Disconnected type:None path:null path: null type: None Java 8 gives the error java.io.IOException: Protocol wrong type for socket WARN - 2018-04-04 09:10:11.879; org.apache.zookeeper.ClientCnxn$SendThread; Session 0x10024db7e280002 for server localhost/0:0:0:0:0:0:0:1:2181, unexpected error, closing socket connection and attempting reconnect java.io.IOException: Protocol wrong type for socket at sun.nio.ch.FileDispatcherImpl.write0(Native Method) at sun.nio.ch.SocketDispatcher.write(SocketDispatcher.java:47) at sun.nio.ch.IOUtil.writeFromNativeBuffer(IOUtil.java:93) at sun.nio.ch.IOUtil.write(IOUtil.java:65) at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:471) at org.apache.zookeeper.ClientCnxnSocketNIO.doIO(ClientCnxnSocketNIO.java:117) at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:366) at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1141) -- CTO, OpenSource Connections Author, Relevant Search http://o19s.com/doug
