[jira] [Resolved] (FLUME-148) text source and tail source are incompatible with unix named pipes

     [ https://issues.apache.org/jira/browse/FLUME-148?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Hsieh resolved FLUME-148.
----------------------------------

    Resolution: Won't Fix

For now we suggest using unix native tail via exec("tail") which can work with named pipes

> In an experiment using named pipes, we found that flume's tail and text sources cannot handle named pipes.  This is because internally these two sources use RandomAccessFiles which use seek commands instead of bytewise streaming reads.
