neo4j - Starting first node in Heo4j HA cluster fails even when allowed to create cluster -

-

whilst trying diagnose different issue cluster tried isolating environments force elections events. when starting nodes in isolation though app failed start exception:

caused by: java.util.concurrent.timeoutexception: null     @ org.neo4j.cluster.statemachine.statemachineproxyfactory$responsefuture.get(statemachineproxyfactory.java:300) ~[neo4j-cluster-2.0.1.jar:2.0.1]     @ org.neo4j.cluster.client.clusterjoin.joinbyconfig(clusterjoin.java:158) ~[neo4j-cluster-2.0.1.jar:2.0.1]     @ org.neo4j.cluster.client.clusterjoin.start(clusterjoin.java:91) ~[neo4j-cluster-2.0.1.jar:2.0.1]     @ org.neo4j.kernel.lifecycle.lifesupport$lifecycleinstance.start(lifesupport.java:503) ~[neo4j-kernel-2.0.1.jar:2.0.1]     ... 59 common frames omitted

my configuration set 60 second join timeout (ha.cluster_join_timeout) , such individual nodes can initialize cluster (ha.allow_init_cluster).

looking @ truncated chunk of code clusterjoin class believe after negative cases code either loop attempting again connect, or current node create new cluster.

private void joinbyconfig() throws timeoutexception {     while( true )         {             if (config.getclusterjointimeout() > 0)             {                 try                 {                     console.log( "joined cluster:" + clusterconfig.get(config.getclusterjointimeout(), timeunit.milliseconds ));                     return;                 }                 catch ( interruptedexception e )                 {                     console.log( "could not join cluster, interrupted. retrying..." );                 }                 catch ( executionexception e )                 {                     logger.debug( "could not join cluster " + this.config.getclustername() );                     if ( e.getcause() instanceof illegalstateexception )                     {                         throw ((illegalstateexception) e.getcause());                     }                      if ( config.isallowedtocreatecluster() )                     {                         // failed join cluster, create new 1                         console.log( "could not join cluster of " + hosts.tostring() );                         console.log( format( "creating new cluster name [%s]...", config.getclustername() ) );                         cluster.create( config.getclustername() );                         break;                     }                      console.log( "could not join cluster, timed out. retrying..." );                 }             }

however timeoutexception not 1 of these cases , in fact joinbyconfig method throws timeoutexception. statemachineproxyfactory$responsefuture class (which implements future) throws timooutexception when time has been waited , no state machine message has been received.

public synchronized object get( long timeout, timeunit unit )             throws interruptedexception, executionexception, timeoutexception     {         if ( response != null )         {             getresult();         }          this.wait( unit.tomillis( timeout ) );          if ( response == null )         {             throw new timeoutexception();         }         return getresult();     }

should case when joining cluster has timed out, , if configured intialise cluster timoutexception should not propagated , new cluster should initialised? if not case, clustered servers have started in unison?

windows - Single EXE to Install Python Standalone Executable for Easy Distribution -

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
