Issues in using tachyon-0.9.0-RC1

[rajans...@gmail.com]

I tried to install tachyon-0.9.0-RC1. I used the same settings as 0.7.1 and started the tachyon cluster. However, now I am having some issues with accessing the worker nodes and the in memory files link, I get the following error
when I click on the In-Memory files link

Also when I click on the individual worker links, I get something like this

Somehow it is not able to find the java class path, I think.

Could you please help resolve the issue? Thanks

Hi,

Thanks for trying out the RC. Yes, the first one is a known issue tracked at https://tachyon.atlassian.net/projects/TACHYON/issues/TACHYON-1668

For the second, did you compile Tachyon with Java 8? And did you use any profiles in your compilation?

Cheers,

Thanks for the info. I am not compiling tachyon myself but using the binary version itself.

Thanks for reporting this issue, this should be fixed in RC-2.

Hope this helps,

Hi Rajansthapit

Thanks for reporting this issue for v0.9.0-RC1. As Calvin mentioned, this issue in unit tests has been fixed in v0.9.0-RC2.

You can either download a tarball with precompiled binaries from

http://tachyon-project.org/downloads/files/0.9.0-RC2/tachyon-0.9.0-RC2-bin.tar.gz

Alternatively, you may check out the Github repo with tag v0.9.0-RC2 and build the binary on your own:

https://github.com/amplab/tachyon/tree/v0.9.0-RC2

Oops, sorry for my typo, I mean, this issue in UI (having unnecessary security check for UI requests) has been fixed, which is not a unittest issue.
