Hi,
Needed help on an issue that is faced when accessing the same Lucene index
on a NFS mounted Unbutu server through different machines configured to
access the same NFS mounted disk.
S/W used:
Lucene: lucene-core-3.0.3
Tomcat : Tomcat 6.0
OS: Ubuntu
1) The same NFS mounted fiel was able to read/write into the same file
through a java program from different m/c in the cluster pointing to the
same NFS mounted disk.
2) But when creating and accessing Lucene Index files on the same NFS
mounted file from two different machines in the cluster caused error
provided below:
Scenario:
* The application reading/writing a Lucene Index on the NFS mounted disk
is hosted on two Tomcat Application server.
* Through one of the App server the Lucene Index is written.
* The same data is able to be retrieved from both the app server. No issues
* Now through one of the App Server updated the existing Lucene Index with
newer data.
* the updated Lucene data is able to be retieved from the same app server
through which update was made.
* But retrieving the same information through the other App Server gives
the error mentioned below. Sometime Read EOF error thrown for the same
scenario.
Could somebody throw some light on what could be the issue? Thanks in
advance.
