-----------------------------------
Summary: Plan nodes with long names lead to invalid dot files
Key: CRUNCH-456
URL: https://issues.apache.org/jira/browse/CRUNCH-456
Project: Crunch
Issue Type: Bug
Reporter: Gabriel Reid
Assignee: Gabriel Reid
When a node in a job plan has a very long name (for example, a job that is
reading from hundreds of different paths as a single input), an invalid dot
file can be created.
Based on simple testing with the dot command (version 2.32 on Mac OS X), it
seems that the node name limit in a dot file is 3000 characters. However, even
this length of node name leads to basically unreadable dot files, so there
should be some kind of abbreviation done on long node names before writing out
job plan dot files.
