Elek, Marton created HDDS-1089: ---------------------------------- Summary: Disable OzoneFSStorageStatistics for hadoop versions older than 2.8 Key: HDDS-1089 URL: https://issues.apache.org/jira/browse/HDDS-1089 Project: Hadoop Distributed Data Store Issue Type: Improvement Components: Ozone Filesystem Reporter: Elek, Marton Assignee: Elek, Marton
HDDS-1033 introduced OzoneFSStorageStatistics for OzoneFileSystem. It uses the StorageStatistics which is introduced in HADOOP-13065 (available from the hadoop2.8/3.0). Using older hadoop (for example hadoop-2.7 which is included in the spark distributions) is not possible any more even with using the isolated class loader (introduced in HDDS-922). Fortunately it can be fixed: # We can support null in storageStatistics field with checking everywhere before call it. # We can create a new constructor of OzoneClientAdapterImpl without using OzoneFSStorageStatistics): If OzoneFSStorageStatistics is not in the method/constructor signature we don't need to load it. # We can check the availability of HADOOP-13065 and if the classes are not in the classpath we can skip the initialization of the OzoneFSStorageStatistics -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
