Description
It would be nice if Impala supported loading plugins for scanning additional text formats aside from LZO - the current logic is fairly specialized but could easily be extended to load libraries for codecs like LZ4 and ZSTD if available. It's kind of weird that we only support that one format.
This might help a bit with IMPALA-6941 and IMPALA-3898 since we could test the plugin-loading mechanism without relying on the external Impala-lzo codebase.
