amazon web services - What would cause Elastic Search to not produce log files? -
i have installed elastic search v5.0 on ubuntu64 virtual machine via debian package given using tutorial elastic
as explained in tutorial sudo -i service elasticsearch start wont give messages here (poor design imo)
i tried adding stdout.log file directory , still empty after starting elastic search
if sudo bin/elasticsearch trace:
exception in thread "main" elasticsearchparseexception[malformed, expected settings start 'object', instead [value_string]] @ org.elasticsearch.common.settings.loader.xcontentsettingsloader.load(xcontentsettingsloader.java:70) @ org.elasticsearch.common.settings.loader.xcontentsettingsloader.load(xcontentsettingsloader.java:50) @ org.elasticsearch.common.settings.loader.yamlsettingsloader.load(yamlsettingsloader.java:50) @ org.elasticsearch.common.settings.settings$builder.loadfromstream(settings.java:938) @ org.elasticsearch.common.settings.settings$builder.loadfrompath(settings.java:927) @ org.elasticsearch.node.internal.internalsettingspreparer.prepareenvironment(internalsettingspreparer.java:102) @ org.elasticsearch.bootstrap.bootstrap.initialenvironment(bootstrap.java:207) @ org.elasticsearch.bootstrap.bootstrap.init(bootstrap.java:247) @ org.elasticsearch.bootstrap.elasticsearch.init(elasticsearch.java:112) @ org.elasticsearch.bootstrap.elasticsearch.execute(elasticsearch.java:103) @ org.elasticsearch.cli.settingcommand.execute(settingcommand.java:54) @ org.elasticsearch.cli.command.mainwithouterrorhandling(command.java:96) @ org.elasticsearch.cli.command.main(command.java:62) @ org.elasticsearch.bootstrap.elasticsearch.main(elasticsearch.java:80) @ org.elasticsearch.bootstrap.elasticsearch.main(elasticsearch.java:73) and without sudo provlidges:

the problem misconfigured elasticsearch.
ensure es uses config file correct location. example, "without sudo priviledges" outputs wrong location.
ensure don't have mistakes in config.
to isolate problem, comment out in config, uncomment line-by-line custom settings in config, , try start. if find line causing problem, check documentation.
also, try start without "-d" option, elasticsearch output full stacktrace in console, , should tell more misconfigured setting.
