Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Arup Malakar

Fix For: 2.8.0

Hadoop streaming exposes all the key values in job conf as environment
variables when it forks a process for streaming code to run. Unfortunately
the variable mapreduce_input_fileinputformat_inputdir contains the list of
input files, and Linux has a limit on size of environment variables +
arguments.
Based on how long the list of files and their full path is this could be
pretty huge. And given all of these variables are not even used it stops user
from running hadoop job with large number of files, even though it could be
run.
Linux throws E2BIG if the size is greater than certain size which is error
code 7. And java translates that to error=7, Argument list too long. More:
http://man7.org/linux/man-pages/man2/execve.2.html I suggest skipping
variables if it is greater than certain length. That way if user code
requires the environment variable it would fail. It should also introduce a
config variable to skip long variables, and set it to false by default. That
way user has to specifically set it to true to invoke this feature.
Here is the exception:

Hadoop streaming throws error if list of input files is high. Error is:
error=7, Argument list too long at if number of input file is high
Key: MAPREDUCE-5965
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5965
Project: Hadoop Map/Reduce
Issue Type: Bug

Hadoop streaming exposes all the key values in job conf as environment
variables when it forks a process for streaming code to run. Unfortunately
the variable mapreduce_input_fileinputformat_inputdir contains the list of
input files, and Linux has a limit on size of environment variables +
arguments.
Based on how long the list of files and their full path is this could be
pretty huge. And given all of these variables are not even used it stops user
from running hadoop job with large number of files, even though it could be
run.
Linux throws E2BIG if the size is greater than certain size which is error
code 7. And java translates that to error=7, Argument list too long. More:
http://man7.org/linux/man-pages/man2/execve.2.html I suggest skipping
variables if it is greater than certain length. That way if user code
requires the environment variable it would fail. It should also introduce a
config variable to skip long variables, and set it to false by default. That
way user has to specifically set it to true to invoke this feature.
Here is the exception:

Thanks guys for good discussions here. +1 on the overall solution here. Agree
that we don't need to put new streaming configuration to *-default.xml as
previous practices.
bq. If you really want to make it configurable the easiest way would be to roll
the two settings in one. We could make the stream.truncate.long.jobconf.values
an integer: -1 do not truncate otherwise truncate at the length given.
That sounds better. May be we should rename
stream.truncate.long.jobconf.values to something like:
stream.jobconf.truncate.limit and document somewhere to say -1 is the default
value which doesn't do any truncate and 20K is a proper value for most cases?

Thanks for the clarification. I'm still getting used to the non-core Hadoop
parts and how those need or don't need to conform.
+1 for the suggested property name and usage better.

Hadoop streaming exposes all the key values in job conf as environment
variables when it forks a process for streaming code to run. Unfortunately
the variable mapreduce_input_fileinputformat_inputdir contains the list of
input files, and Linux has a limit on size of environment variables +
arguments.
Based on how long the list of files and their full path is this could be
pretty huge. And given all of these variables are not even used it stops user
from running hadoop job with large number of files, even though it could be
run.
Linux throws E2BIG if the size is greater than certain size which is error
code 7. And java translates that to error=7, Argument list too long. More:
http://man7.org/linux/man-pages/man2/execve.2.html I suggest skipping
variables if it is greater than certain length. That way if user code

[~amalakar] thank you for the assignment. The comment should be added back,
I'll do that with an updated patch. The move to keep it in the same method was
to make the change as simple as possible.
[~rchiang]
The streaming configuration does not really have a *-default.xml file. There is
documentation (markdown) that shows some of the settings and options: adding it
to the FAQ would probably be the correct place. There is a help that is printed
in the main StreamJob code that shows most of the options. I will update the
two files and explain the setting that is available. I can upload a new patch
with that added before I do lets get the other points finalised.
A white list or black list is possible but what would we exclude or include? In
the job configuration there could be any value which could be too long, a user
could set something he wants. It will be really difficult to filter that
consistently and be sure that we have a fix with limited impact.
Making the lenLimit configurable is possible. However I do not see what we
would win with making the length configurable. The data is not used anywhere
and lowering or increasing the size at which we cut it off will not give us
anything extra. If you really want to make it configurable the easiest way
would be to roll the two settings in one. We could make the
stream.truncate.long.jobconf.values an integer: -1 do not truncate otherwise
truncate at the length given.

[~wilfreds] sure. Just a comment in the patch I had submitted the check was
inside a separate function with some comment on why we want to do it. As can be
seen in:

Is there a reason to remove those?

Thanks Wilfred. I guess I'll comment on the meta issue first. In general, I'm
not sure whether it's a good idea to filter based purely on size. Would it
better to have a more firm whitelist and/or blacklist capability for Hadoop
streaming?

Making these comments assuming the current patch is an acceptable design
approach, I have the following nitpicks:
1) Can stream.truncate.long.jobconf.values be put in the appropriate
*-default.xml file for documentation purposes?
2) Can the lenLimit correspond to a Configuration variable?

MAPREDUCE-5965.patch
Hadoop streaming exposes all the key values in job conf as environment
variables when it forks a process for streaming code to run. Unfortunately
the variable mapreduce_input_fileinputformat_inputdir contains the list of
input files, and Linux has a limit on size of environment variables +
arguments.
Based on how long the list of files and their full path is this could be
pretty huge. And given all of these variables are not even used it stops user
from running hadoop job with large number of files, even though it could be
run.
Linux throws E2BIG if the size is greater than certain size which is error
code 7. And java translates that to error=7, Argument list too long. More:
http://man7.org/linux/man-pages/man2/execve.2.html I suggest skipping
variables if it is greater than certain length. That way if user code
requires the environment variable it would fail. It should also introduce a
config variable to skip long variables, and set it to false by default. That
way user has to specifically set it to true to invoke this feature.
