Method Detail

hasTag

boolean hasTag()

required string tag = 1;

Returns:

Whether the tag field is set.

getTag

String getTag()

required string tag = 1;

Returns:

The tag.

getTagBytes

com.google.protobuf.ByteString getTagBytes()

required string tag = 1;

Returns:

The bytes for tag.

hasPositionShort

boolean hasPositionShort()

 is position short or not, used for HDFS performance optimization.
 When the client buffer size is large ( > 2MB) and reads are guaranteed to be somewhat
 sequential, the `pread` API to HDFS is not as efficient as simple `read`.
 We introduce a heuristic to choose which API to use.
 

required bool position_short = 2;

Returns:

Whether the positionShort field is set.

getPositionShort

boolean getPositionShort()

 is position short or not, used for HDFS performance optimization.
 When the client buffer size is large ( > 2MB) and reads are guaranteed to be somewhat
 sequential, the `pread` API to HDFS is not as efficient as simple `read`.
 We introduce a heuristic to choose which API to use.
 

required bool position_short = 2;

Returns:

The positionShort.

hasBandwidth

boolean hasBandwidth()

optional int64 bandwidth = 3;

Returns:

Whether the bandwidth field is set.

getBandwidth

long getBandwidth()

optional int64 bandwidth = 3;

Returns:

The bandwidth.

hasUser

boolean hasUser()

optional string user = 4;

Returns:

Whether the user field is set.

getUser

String getUser()

optional string user = 4;

Returns:

The user.

getUserBytes

com.google.protobuf.ByteString getUserBytes()

optional string user = 4;

Returns:

The bytes for user.
