      Description

      My team and another user from the mailing list have run into an issue where replacing the coprocessor jar in HDFS and reloading the table does not load the latest jar. It may load the latest version on some percentage of RS but not all of them.

      This may be a config oversight or a lack of understanding of a caching mechanism that has a purge capability, but I thought I would log it here for confirmation.

      Workaround is to name the coprocessor JAR uniquely, place in HDFS, and re-enable the table using the new jar's name.
