      After HBASE-26714, users of hbase can now set system coprocessor with a path of the JAR file other than the files in default classpath. E.g. when setting hbase.coprocessor.region.classes/hbase.coprocessor.regionserver.classes/hbase.coprocessor.user.region.classes/hbase.coprocessor.master.classes, user can set a comma-separated list with the format of className|priority|path, where the path could be a file path of the supported filesystem.

    Description

      Currently when region server starts, system coprocessors are normally loaded as part of the local classpath and the jar is stored in the local storage; in short words, Operator would have to copy the jar to each host (or a shared file system) and construct it as part of HBASE_CLASSPATH.

      although operator may have been doing the presetup of copying jar and making it available to the HBASE_CLASSPATH without any issue, it could be helpful if we provide an alternative method and centralize this configuration in hbase-site similar to the support of table-level coprocessor, e.g. configuring hbase.coprocessor.region.classes with the local/remote path along with the classname with a specific path token in the form of className|priority|path.

      Similarly in HBASE-23710, it provided the priority configuration via hbase-site that this new improvement aligns with the same purpose, and further help to simplify the deployment of System Coprocessors to e.g. hdfs or supported cloud storage.
