First time user - Error

[vaishnav kovvuri]

Hi,

 I performed the steps mentioned at http://tachyon-project.org/Running-Tachyon-Locally.html and the tried to access the webpage http://localhost:19999 to verify if tachyon is running. I experience the following error. I am still debugging this, but wondering if anyone experienced the same.

Thanks,

Vaishnav

I have had a similar issue where Jasper said there was no jdk (though I was running via a jdk). The workaround we used was to add "-Dorg.apache.jasper.compiler.disablejsr199=true" to TACHYON_JAVA_OPTS in tachyon-env.sh, to make it stop trying to compile stuff.

Thanks Aaron.

Vaishnav,

Does the fix work? The "-Dorg.apache.jasper.compiler.disablejsr199=true" in also in the tachyon-env.sh.template.

Cheers,

Haoyuan

Haoyuan,

 Thanks Aaron. No, it did not help me. Still encountering the error.

Thanks,

What version of java are you using?  I know that the current code doesn't work with java 8.

[vaishnav kovvuri]

I tried both java8 & java7. UI is giving me error.

when I run "./bin/tachyon runTest Basic CACHE_THROUGH", tests are all successful. That's at least good.

Still I cannot see anything in UI.

[Haoyuan Li]

Could you copy and paste your tachyon-env.sh?

Just to close the loop - I re-imaged my machine with ubuntu 12.04 LTS and everything (including webpage) came up correctly.

Thanks,

Vaishnav

[David Capwell]

Thanks for the feedback.  Can you tell us what the system was like before?

[vaishnav kovvuri]

Before I used Centos6.5 and now ubuntu 12.04LTS
