Summary: Remove/deprecate s3native properties from S3NativeFileSystemConfigKeys and core-default.xml Key: HADOOP-12981 URL: https://issues.apache.org/jira/browse/HADOOP-12981 Project: Hadoop Common Issue Type: Improvement Components: tools Affects Versions: 3.0.0 Reporter: Wei-Chiu Chuang Priority: Minor It seems all properties defined in {{S3NativeFileSystemConfigKeys}} are not used. Additionally, core-default.xml has the description of these unused properties: {noformat} <!-- s3native File System --> <property> <name>s3native.stream-buffer-size</name> <value>4096</value> <description>The size of buffer to stream files. The size of this buffer should probably be a multiple of hardware page size (4096 on Intel x86), and it determines how much data is buffered during read and write operations.</description> </property> <property> <name>s3native.bytes-per-checksum</name> <value>512</value> <description>The number of bytes per checksum. Must not be larger than s3native.stream-buffer-size</description> </property> <property> <name>s3native.client-write-packet-size</name> <value>65536</value> <description>Packet size for clients to write</description> </property> <property> <name>s3native.blocksize</name> <value>67108864</value> <description>Block size</description> </property> <property> <name>s3native.replication</name> <value>3</value> <description>Replication factor</description> </property> {noformat} I think they should be removed (or deprecated) to avoid confusion if these properties are defunct. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
