> Set textinputformat.record.delimiter as "</entity>"
> Suppose the input is a text file with the following content
> <entity><id>1</id><name>User1</name></entity><entity><id>2</id><name>User2</name></entity><entity><id>3</id><name>User3</name></entity><entity><id>4</id><name>User4</name></entity><entity><id>5</id><name>User5</name></entity>
> Mapper was expected to get value as 
> Value 1 - <entity><id>1</id><name>User1</name>
> Value 2 - <entity><id>2</id><name>User2</name>
> Value 3 - <entity><id>3</id><name>User3</name>
> Value 4 - <entity><id>4</id><name>User4</name>
> Value 5 - <entity><id>5</id><name>User5</name>
> According to this bug Mapper gets value
> Value 1 - entity><id>1</id><name>User1</name>
> Value 2 - <entity>id>2</id><name>User2</name>
> Value 3 - <entity><id>3id><name>User3</name>
> Value 4 - <entity><id>4</id><name>User4name>
> Value 5 - <entity><id>5</id><name>User5</name>
> The pattern shown above need not occur for value 1,2,3 necessarily. The bug occurs at
some random positions in the map input.
