Examples with CacheEvictionStatsBuilder org.apache.hadoop.hbase.CacheEvictionStatsBuilder used on opensource projects

Example 1 with CacheEvictionStatsBuilder

use of org.apache.hadoop.hbase.CacheEvictionStatsBuilder in project hbase by apache.

the class RSRpcServices method clearRegionBlockCache.

@Override
public ClearRegionBlockCacheResponse clearRegionBlockCache(RpcController controller, ClearRegionBlockCacheRequest request) throws ServiceException {
    rpcPreCheck("clearRegionBlockCache");
    ClearRegionBlockCacheResponse.Builder builder = ClearRegionBlockCacheResponse.newBuilder();
    CacheEvictionStatsBuilder stats = CacheEvictionStats.builder();
    List<HRegion> regions = getRegions(request.getRegionList(), stats);
    for (HRegion region : regions) {
        try {
            stats = stats.append(this.server.clearRegionBlockCache(region));
        } catch (Exception e) {
            stats.addException(region.getRegionInfo().getRegionName(), e);
        }
    }
    stats.withMaxCacheSize(server.getBlockCache().map(BlockCache::getMaxSize).orElse(0L));
    return builder.setStats(ProtobufUtil.toCacheEvictionStats(stats.build())).build();
}

Example 2 with CacheEvictionStatsBuilder

use of org.apache.hadoop.hbase.CacheEvictionStatsBuilder in project hbase by apache.

the class ProtobufUtil method toCacheEvictionStats.

public static CacheEvictionStats toCacheEvictionStats(HBaseProtos.CacheEvictionStats stats) throws IOException {
    CacheEvictionStatsBuilder builder = CacheEvictionStats.builder();
    builder.withEvictedBlocks(stats.getEvictedBlocks()).withMaxCacheSize(stats.getMaxCacheSize());
    if (stats.getExceptionCount() > 0) {
        for (HBaseProtos.RegionExceptionMessage exception : stats.getExceptionList()) {
            HBaseProtos.RegionSpecifier rs = exception.getRegion();
            byte[] regionName = rs.getValue().toByteArray();
            builder.addException(regionName, ProtobufUtil.toException(exception.getException()));
        }
    }
    return builder.build();
