Jerome Boulon commented on CHUKWA-306:
--------------------------------------
Backfill do not open any port so there's no issue.
But the port number cannot be randomized since you want to get jobHistory from
Hadoop so Hadoop needs to know where to send the information.
An option if you don't want to have one agent per machine, will be to use
Zookeeper to coordinate everything but it will be more complicated to deploy
not less
> Standalone (non-daemon) Chukwa operation
> ----------------------------------------
>
> Key: CHUKWA-306
> URL: https://issues.apache.org/jira/browse/CHUKWA-306
> Project: Hadoop Chukwa
> Issue Type: Wish
> Reporter: Jiaqi Tan
> Priority: Critical
>
> This is an articulation of a possible alternative use of Chukwa as a
> standalone log analysis pipeline. This would enable users to read in existing
> logs from files, process (Demux) and perform analysis (e.g. current
> SALSA/Mochi toolchain) on them, and visualize them, without requiring the
> user to setup or run any daemons, nor database servers.
> This can be presented as an alternative interface to Chukwa for the user,
> where the main architectural parts (Chunks, post-Demux SequenceFiles of
> ChukwaRecords, post-Demux-processing SequenceFiles of ChukwaRecords, and
> finally time-aggregated database entries for fast visualization) remain
> unchanged, and Chukwa is manifest as a set of files in HDFS. The main value
> that Chukwa then provides to users is 1. centralized one-stop-shop for log
> processing+analysis+anomaly detection, 2. the ability to use MapReduce to
> process logs, regardless of whether they had used Chukwa to collect the logs.
> That way, the ability to process logs and analyze/do diagnosis is not tied to
> having to run the entire Chukwa daemon infrastructure, since many users who
> use Hadoop clusters may not have superuser access to those machines, e.g.
> users at universities using shared clusters.
