> ClassCastException in cache group metrics on client nodes
> ---------------------------------------------------------
>
> Key: IGNITE-13100
> URL: https://issues.apache.org/jira/browse/IGNITE-13100
> Project: Ignite
> Issue Type: Bug
> Reporter: Alexey Goncharuk
> Assignee: Alexey Goncharuk
> Priority: Major
> Fix For: 2.9
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> The following exception can be observed when reading cache group metrics on
> client nodes with persistence-enabled config:
> {code}
> java.lang.ClassCastException:
> org.apache.ignite.internal.processors.cache.persistence.IgniteCacheDatabaseSharedManager
> cannot be cast to
> org.apache.ignite.internal.processors.cache.persistence.GridCacheDatabaseSharedManager
> at
> org.apache.ignite.internal.processors.cache.CacheGroupMetricsImpl.database(CacheGroupMetricsImpl.java:506)
> at
> org.apache.ignite.internal.processors.cache.CacheGroupMetricsImpl.lambda$new$0(CacheGroupMetricsImpl.java:103)
> at
> org.apache.ignite.internal.util.lang.GridFunc.lambda$nonThrowableSupplier$3(GridFunc.java:3341)
> at
> org.apache.ignite.internal.processors.metric.impl.LongGauge.value(LongGauge.java:45)
> at
> org.apache.ignite.spi.metric.LongMetric.getAsString(LongMetric.java:29)
> {code}
> The reason is an incomplete check for persistence enabled in
> {{CacheGroupMetricsImpl}}: we should also check for client nodes.
> Suggested solution: include the check for client node mode for database
> metrics readings
