> HDFS Caching with Impala:
> If we create a pool specifying the maxTtl with the hdfs command:
> e.g:
> {{sudo -u hdfs hdfs cacheadmin -addPool foo -owner impala -group hdfs -mode
> 755 -limit 100000000000 -maxTtl 7d}}
> when we try to alter a table adding a partition in Impala:
> e.g:
> {code:java}
> alter table foo partition (p1=1) set cached in 'foo'
> {code}
> we get a failure with the exception:
> {code:java}
> ERROR: ImpalaRuntimeException: Expiration 26687997791:19:48:13.951 exceeds
> the max relative expiration time of 604800000 ms.

> this is always reproducible.
> The workaround is to do not set the maxTtl in the hdfs command during the
> pool creation.
> Here's the repro steps:
> {code:java}
> impala-shell -i <ImpalaD hostname> -q "drop table if exists foo;"
> impala-shell -i <ImpalaD hostname> -q "create table if not exists foo (c1
> int, c2 string) partitioned by (p1 int) stored as parquet location
> '/user/hive/warehouse/foo';"
> impala-shell -i <ImpalaD hostname> -q "insert into foo partition (p1 = 1 )
> values (1 ,'one');"
> sudo -u hdfs hdfs cacheadmin -removePool foo
> sudo -u hdfs hdfs cacheadmin -listDirectives -stats
> sudo -u hdfs hdfs cacheadmin -listPools -stats
> sudo -u hdfs hdfs cacheadmin -addPool foo -owner impala -group hdfs -mode 755
> -limit 100000000000 -maxTtl 7d
> sudo -u hdfs hdfs cacheadmin -addDirective -path /user/hive/warehouse/foo
> -pool foo -ttl 7d
> sudo -u hdfs hdfs cacheadmin -listDirectives -stats
> sudo -u hdfs hdfs cacheadmin -listPools -stats
> impala-shell -i <ImpalaD hostname> -q "alter table foo set uncached;"
> sleep 5;
> impala-shell -i <ImpalaD hostname> -q "alter table foo partition (p1=1) set
> cached in 'foo';"
> {code}
> I did not found any already open jira for this issue that looks reproducible
> in many CDH versions, I appreciate if you can take a look on it.
