IllegalAccessError when using an MVEL script filter in the query

Connie_Yang · May 25, 2013, 1:58am

Hi,

We have a 2-node ES cluster running 0.90.0 release in our QA environment.
When we started using a script filter in our query, we got the following
stack trace after a few queries to ES. After looking into the issue a bit,
the issue seemed to be caused by the use of MVEL in compiled or accelerated
mode. Further research seems to indicate that disabling JIT for MVEL
worked around the problem (via -Dmvel2.disable.jit=true).

Disabling MVEL JIT would also mean a performance concern for us. What's
root cause of this issue? How should we address it?

Also, if we want to use a script filter, which scripting language would you
recommended?

Thanks,

that's not good. Can you provide more info about your system like JVM
version and vendor etc. and maybe the script you try to run?
this seems to be worth an issue too, can you open one?

that's not good. Can you provide more info about your system like JVM
version and vendor etc. and maybe the script you try to run?
this seems to be worth an issue too, can you open one?

Hi,

We have a 2-node ES cluster running 0.90.0 release in our QA
environment. When we started using a script filter in our query, we got
the following stack trace after a few queries to ES. After looking into
the issue a bit, the issue seemed to be caused by the use of MVEL in
compiled or accelerated mode. Further research seems to indicate that
disabling JIT for MVEL worked around the problem (via
-Dmvel2.disable.jit=true).

Disabling MVEL JIT would also mean a performance concern for us. What's
root cause of this issue? How should we address it?
