Hi all.

When a writer for a column family exceeds the hregion.max.filesize  then we=
 are rolling writers of all the column families though the writers of the o=
ther column family has not exceeded the max size.
Below is the code snippet from HFileOutputFormat2 class.
{code}
        // If any of the HFiles for the column families has reached
        // maxsize, we need to roll all the writers
        if (wl !=3D null && wl.written + length >=3D maxsize) {
          this.rollRequested =3D true;
        }

        // This can only happen once a row is finished though
        if (rollRequested && Bytes.compareTo(this.previousRow, rowKey) !=3D=
 0) {
          rollWriters();
        }
{code}

Is it a bug or I am missing something ?

Regards,
Ashish Singhi
