Phoenix Tips (12) 跟踪 Tracing

只支持Hadoop2

配置 hadoop-metrics2-phoenix.properties

# Sample from all the sources every 10 seconds
*.period=10

# Write Traces to Phoenix
##########################
# ensure that we receive traces on the server

# Tell the sink where to write the metrics
phoenix.sink.tracing.writer-class=org.apache.phoenix.trace.PhoenixTableMetricsWriter
# Only handle traces with a context of "tracing"
phoenix.sink.tracing.context=tracing

配置 hadoop-metrics2-hbase.properties

The tracing table is initialized via the ddl:

    CREATE TABLE SYSTEM.TRACING_STATS (
      trace_id BIGINT NOT NULL,
      parent_id BIGINT NOT NULL,
      span_id BIGINT NOT NULL,
      description VARCHAR,
      start_time BIGINT,
      end_time BIGINT,
      hostname VARCHAR,
      tags.count SMALLINT,
      annotations.count SMALLINT,
      CONSTRAINT pk PRIMARY KEY (trace_id, parent_id, span_id)
