setting up alluxio.worker.tieredstore.levels=2 is giving me parsing exception

[Mayuresh Pandey]

Hi Guys,

I am not able to figure out when I try to set it up this (alluxio.worker.tieredstore.levels=2) parameter worker is not getting started and end up in exception below.

2016-09-13 15:04:34,552 ERROR logger.type (AlluxioWorker.java:<init>) - Failed to initialize alluxio.worker.AlluxioWorker

java.lang.RuntimeException: Configuration cannot evaluate key alluxio.worker.tieredstore.levels as integer

        at alluxio.Configuration.getInt(Configuration.java:242)

        at alluxio.StorageTierAssoc.<init>(StorageTierAssoc.java:43)

        at alluxio.worker.AlluxioWorker.<init>(AlluxioWorker.java:157)

        at alluxio.worker.AlluxioWorker.get(AlluxioWorker.java:104)

        at alluxio.worker.AlluxioWorker.main(AlluxioWorker.java:82)

Any idea, When I comment this parameter worker get starts but Storage usage summary does not show HDD or SDD. Only MEM is visible.

Hi Mayuresh,

I used the file you attached for alluxio-site.properties of a new Alluxio 1.2 deployment and the system came up fine:

​

The one thing I did, was to remove the ALLUXIO_WORKER_MEMORY_SIZE setting from conf/alluxio-env.sh to prevent it from overriding the one in the properties file. But even without this change, the cluster would come up fine (with the correct number of tiers).

One thing for you to try would be to add a log statement to the getInt method to actually print the value that fails to parse as an integer. I suspect it will not be "2".

Best,
