    Affects Versions: Impala 2.8.0
            Reporter: Lars Volker
            Priority: Critical


Frontend::ExecHiveServer2MetadataOp() seems to trigger a JNI exception, which results in a segmentation fault in {{libjvm.so!jni_GetStringUTFChar}}.

Here is the stack trace of the crashing thread from a minidump.
