Summary: Shared fetch enabled fetches all partitions on task 0000s directly to disk for non-broadcast edges Key: TEZ-4571 URL: https://issues.apache.org/jira/browse/TEZ-4571 Project: Apache Tez Issue Type: Improvement Reporter: Jonathan Turner Eagles I think the idea of shared fetch is to fetch once per node for broadcast input. However, the enabled in the fetcher doesn't check the edge type but only that 1) shared fetch is enabled and 2) task for the vertex is 0000. For broadcast edge this is correct perhaps, but for non-broadcast edges, all partitions are fetched to disk without possibility of sharing -- This message was sent by Atlassian Jira (v8.20.10#820010)
