Subject: [Swift-user] Swift-MosaStore integration problem<br>> Dear All,<br>> <br>> <br>> <br>> <br>> <br>> <br>> <br>> When I try to run the HelloWorld.swift with MosaStore (MosaStore is a<br>> distributed storage developed by us) it is terminating with an error.<br>> <br>> <br>> <br>> Here HelloWorld.swift script is copied into the MosaStore filesystem.<br>> Also Swift has write permission in the file system. Because it can<br>> create some temporary files (swift.log and<br>> first-20111026-1848-hmo97vu7.log). But then it prints the error below<br>> and terminates (I have attached the log files. I am using swift 0.93).<br>> <br>> <br>> <br>> Max heap: 259522560<br>> Recompilation suppressed.<br>> Detailed exception:<br>> java.io.FileNotFoundException: /tmp/mount/dir1/first.kml (No such file<br>> or directory)<br>> at java.io.FileInputStream.open(Native Method)<br>> at
java.io.FileInputStream.<init>(FileInputStream.java:137)<br>> at java.io.FileInputStream.<init>(FileInputStream.java:96)<br>> at java.io.FileReader.<init>(FileReader.java:58)<br>> at org.globus.cog.karajan.Loader.load(Loader.java:209)<br>> at org.griphyn.vdl.karajan.Loader.main(Loader.java:157)<br>> Could not start execution.<br>> /tmp/mount/dir1/first.kml (No such file or directory)<br>> <br>> <br>> It seems the Mosastore didnt receive any callback to create first.kml.<br>> I think, due to some reasons JVM assumes the storage is not available<br>> and terminate the swift program. So I am wondering whether you can<br>> provide any hint about this issue.<br>> <br>> Also I would like to build the swift in debug mode in order to run it<br>> with jdb (to get more information). Please let me know how to build<br>> the swift in debug mode?<br>> <br>> <br>> Thank you<br>>
