Alan Gates commented on HIVE-13680:
-----------------------------------
bq. If the server does not have that compressor plugin, it will request the jar
from the client. The client should send the compressor plugin and all
dependencies.
We should not do this. It is a code injection security issue. We cannot have
users sending code into HS2 and the task nodes without full security controls.
In this case it makes more sense to make sure that we provide compressors for
the standard options Hadoop already supports (snappy, lzo, ...)
Can the existing (de)compressors already in use in ORC etc. be used for this
rather than re-implementing?
