Pivotal GemFire 7.x-188.8.131.52
This article discusses how to resolve a gfsh hang issue that may occur when running [gfsh start]/[gfsh status].
When using the "gfsh start" command to start a locator or a cache server or when using the "gfsh status" command to confirm GemFire member process status, the gfsh shell may not return a result. Or, it may simply continue showing "......." in the console while the GemFire member process does start correctly or is in a healthy status.
There is an underlying issue, GEM-809/GEODE-1387 involving a race condition in the file-based support for the [gfsh start] and [gfsh status] commands.
With these two commands, if the JDK's tools.jar is not in the CLASSPATH, gfsh will use a file-based implementation for [gfsh start] and [gfsh status] and may encounter a hang issue during [gfsh start] or [gfsh status] execution. (The [gfsh start] command uses the [gfsh status] routine to determine if startup is complete.)
When the tools.jar is in the CLASSPATH, the [gfsh start]/[gfsh status] commands will use the tools.jar's API which will not hit this hang issue.
This issue is fixed with GemFire 184.108.40.206+/Gemfire9.x. and may be avoided or worked around in earlier versions by adding the tools.jar to the CLASSPATH of gfsh and any locator/server.
