Elasticsearch 2.0.0beta1 does not start if ES_GC_LOG_FILE value is set in init file.

[ajaybhatnagar]

No logs generated for ES (in Debug mode) or system log. process does not start at all. Commenting the line , elasticsearch starts with no issues. Tried creating directory path and empty file with full permission on gc.log ES_GC_LOG_FILE=/var/log/elasticsearch/gc.log, still unable to start with no error message any where.

@ajaybhatnagar when I specify it on the command line, I get this error:

» ES_GC_LOG_FILE=/tmp/foo/gc.log bin/elasticsearch
Invalid file name for use with -Xloggc: Filename can only contain the characters [A-Z][a-z][0-9]-_.%[p|t] but it has been "/tmp/foo/gc.log"
Note %p or %t can only be used once
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Which file are you putting it in? It could be the same error but just not being printed to the right place.

Note that even if I specify a super simple log filename ("foo"), I still get the same error, so I think this is a bug:

» ES_GC_LOG_FILE=foo bin/elasticsearch
Invalid file name for use with -Xloggc: Filename can only contain the characters [A-Z][a-z][0-9]-_.%[p|t] but it has been "foo"
Note %p or %t can only be used once
