This appears to have been caused by orc.write.variable.length.blocks=true which
I had set for HDFS-based tables. Setting this to false and inserting data into
the S3 table appears to have fixed this problem.

Subject: LLAP can't read ORC ZLIB files from S3
Hello everyone,
I'm encountering an error that I can't find any information on. I've inserted
data into a table with storage in S3 in ORC ZLIB format. I can query this data
directly without issues. Running a query that requires LLAP causes the
following error:

This is specific to ORC ZLIB files on S3 being processed through LLAP. I can
query other types of files in S3 through LLAP, I can query the ORC ZLIB data on
S3 directly (select * from orc_zlib_on_s3_table limit 10) and I can execute the
same query that fails in LLAP in Native Tez containers. Does anyone have any
suggestions as to what the problem might be or how to debug it?
Thanks,
Aaron
