Я пытаюсь протестировать HBase 2.0.0 с YCSB 0.15. Hbase может создавать таблицы и отлично работает. Однако, когда я запускаю следующую команду
./bin/ycsb load hbase20 -P workloads/workloada -p columnfamily=family
Я получаю следующие предупреждения и ошибки (немного извините, пожалуйста):
log4j:WARN No appenders could be found for logger (org.apache.htrace.core.Tracer).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Starting test.
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
