-----------------------------
Summary: Samoa AvroFileStream from HDFSFileStreamSource stops at
end of first file
Key: SAMOA-58
URL: https://issues.apache.org/jira/browse/SAMOA-58
Project: SAMOA
Issue Type: Bug
Components: SAMOA-Instances
Environment: RHEL 6.6, java 1.8.0_72
Reporter: Edi Bice
It appears Samoa is capable of streaming a collection of files as a single
stream effectively concatenating the files. However using Samoa AvroFileStream
from HDFSFileStreamSource seems the stream stops at end of first file:
