Vitalii Diravka updated DRILL-6282:
-----------------------------------
Description:
There are three types of metrics in Drill:
1. _com.yammer.metrics_,
2. _com.codahale.metrics_,
3. _io.dropwizard.metrics_
Directly Drill uses only 2. The 1 and 3 ones are used as transitive
dependencies only.
The 2 and 3 ones have the same class full identifiers and maven doesn't know
which library to use ([https://github.com/dropwizard/metrics/issues/1044]).
The 2 one is an outdated, but the 3 one is still under developing and updating.
Therefore the decision is:
* to use only one _io.dropwizard.metrics_ Metrics for Drill,
* to remove _com.codahale.metrics_ metrics,
* to control under dependency management block _com.yammer.metrics_ Metrics.
was:
There are three types of metrics-core in Drill:
1. _com.yammer.metrics_,
2. _com.codahale.metrics_,
3. _io.dropwizard.metrics_
Drill uses only 1 and 2. The last 3 one is used by Hive.
1st one has different class full identifiers, but the 2 and 3 ones have the
same class full identifiers and maven doesn't know which library to use
([https://github.com/dropwizard/metrics/issues/1044]).
But I found that 3 one library is used by Hive only for tests, therefore it is
not required for Drill and could be excluded from hive-metastore and hive-exec.
The dependencies conflict is related not only to metrics-core, but to
metrics-servlets and metrics-json as well.
All these metrics should be organized with proper excluding and dependency
management blocks.
