----------------------------
Summary: multilang seems had read from pipe but didn't clear the
spout process's STDOUT
Key: STORM-459
URL: https://issues.apache.org/jira/browse/STORM-459
Project: Apache Storm (Incubating)
Issue Type: Bug
Reporter: seanXh
Hi,All
I'am using the storm's multilang throughing PHP. But it seems have some
problem.
Then my spout is a php script which read contents from a file.And in the
beginning of the 4Mb content,which runs correctly.But the php process will
blocks in the write(1,xxxx...,when i strace -p the php spout.
But when i use 'cat' read from the /proc/pid/fd/1 which is the php process
STDOUT. All of the content had been handle correctly in the bolt is still there.
So, i doubt that spout hangs out when write(1,xxx , is because that the
process's STDOUT buffer is full of contents. But how can i prevent this issue.
My environment is
Linux : 2.6.32_1-9-3-1 kernel.
Java: 1.6.0_33
Storm:0.8.2 or 0.8.1
PHP: 5.2
Thx
Sean
