We are evaluating GFS for use as a highly concurrent distributed file system.
What I have observed:
When 2 JVM's (multiple Threads per Java Virtual Machine) are writing to the same directory on GFS, on of the JVM doesn't see the files it writes on the GFS.
The Writer Threads on JVM think they're done, but the files don't show up on "ls" etc.
The other JVM works fine.
This problem goes away if the 2 JVM's write to different directories on GFS
OR
Only one JVM is writing at a time.
Any ideas on this.
