Добрый день всем
Поставил виртуалку хадуповскую от Клаудеры.
Были варнинги но все пахало 2 дня.
http://www.cloudera.com/developers/get-started-with-hadoop-tutorial/setup.html
все сервисы были зеленые
прихожу через день (не выключал ВМ)- крансые кружки HDFS не стартован
рестартовал и ВМ и комп безсполезно - 2 день мучаюсь
В линуксе сам не силен.

вот картинки

safe mode status bad.

Bad : Canary test failed to create file in directory /tmp/.cloudera_health_monitoring_canary_files.
A failure of this health test may indicate that the cluster is failing to satisfy basic client requests correctly or in a timely fashion.
Check the status of the NameNode and other service-level health tests.

Look in the Service Monitor logs for log messages from the canary test.
Look in the NameNode logs for more details about the processing of the canary test requests.

> hdfs/hdfs.sh ["dfsadmin","-fs","hdfs://quickstart.cloudera:8020","-safemode","leave"]
The NameNode successfully left Safemode.

Но все равно не пашет.


зы менялся IP адрес ВМ - может это быть связаоно с этим (хотя все работало)?

Current warnings :
но вроде пахало как то и с ворнингами
(на компе 16 гиг
на виртуалку выделил 10 гиг - маловато но вроде работало)


Cloudera QuickStart

ZooKeeper: Service zookeeper has 1 Server. Cloudera suggests at least 3 Servers for ZooKeeper. Suppress...
HDFS: Service hdfs has 1 DataNode. Cloudera suggests at least 3 DataNodes for HDFS. Suppress...
HDFS: Java Heap Size of NameNode in Bytes Suppress...
Java Heap Size of NameNode in Bytes is recommended to be at least 1GB for every million HDFS blocks. Suggested minimum value: 4294967296
quickstart.cloudera: Memory Overcommit Validation Threshold Suppress...
Memory on host quickstart.cloudera is overcommitted. The total memory allocation is 18.2 GiB bytes but there are only 10.1 GiB bytes of RAM (2.0 GiB bytes of which are reserved for the system). Visit the Resources tab on the Host page for allocation details. Reconfigure the roles on the host to lower the overall memory allocation. Note: Java maximum heap sizes are multiplied by 1.3 to approximate JVM overhead.
