Describe the solution you are proposing
Remove the<OS_HOME>/performance-analyzer-rca folder from the OS home directory. This way there is only one location for PA plugin and PA-RCA process: <OS_HOME>/plugins/opensearch-performance-analyzer.

Contents of <OS_HOME>/performance-analyzer-rca before:

bin  lib  pa_bin  pa_config

pa_bin and pa_config in <OS_HOME>/performance-analyzer-rca and <OS_HOME>/plugins/opensearch-performance-analyzer were exactly the same. Hence, no action needs to be taken for these two folders.

Copy bin into <OS_HOME>/plugins/opensearch-performance-analyzer and rename as rca_bin.

Copy lib into <OS_HOME>/plugins/opensearch-performance-analyzer and rename as rca_lib. Remove all the common library files between <OS_HOME>/plugins/opensearch-performance-analyzer and <OS_HOME>/plugins/opensearch-performance-analyzer/rca_lib so as to reduce the memory footprint.
