[jira] [Updated] (KAFKA-10565) Console producer displays
interactive prompt even when input is not interactive
[ https://issues.apache.org/jira/browse/KAFKA-10565?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sergei Morozov updated KAFKA-10565:
-----------------------------------
Description:
The prompt introduced in KAFKA-2955 may be indeed helpful when a user enters messages manually but when the messages are read from the file, it's not helpful and may be really annoying.
h5. Steps to reproduce
# Create a file with a decent number of messages (e.g. 80,000 in my case)
# Start console producer and forward the file contents to its STDIN:
$ kafka-console-producer --broker-list b1,b2,b3 {{--topic test < messages.txt}}
{{>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> ... >>>>>>>>>>>>>>}}
For each message the producer reads from the file, there's one > displayed polluting the output.
h5. Expected behavior:
# If the producer can detect that the input stream is a TTY, it should not display the prompt.
# Ideally, there should be a configuration parameter to disable this explicitly.
