Change subject: IMPALA-13076 Add pstack and jstack to Impala Redhat docker images ...................................................................... IMPALA-13076 Add pstack and jstack to Impala Redhat docker images When the Impala docker images are deployed in production environments, it can be hard to add debugging tools at runtime. Two of the most useful diagnosis tools are jstack and pstack, which can be used to find Java and native stack traces. Install these tools into Redhat images which are the most commonly used in production. To install pstack we install gdb To install jstack we install a development jdk instead of the previous headless jdk. In a Centos 8.5 build, the size of a impalad_coord_exec image increased from 1.74GB to 1.85GB, as reported by ‘docker image list’. What other tools might be added? - Installing perf is tricky as in a container perf requires an installation specific to the underlying linux kernel image, which is hard to predict at build time. - Installing pprof is hard as installation seems to require compiling from sources. Clearly there are many options and we cannot install everything. TESTING Built the docker images, and used jstack and pstack in a running container to print Impala's stacks.
