Kousuke Saruta commented on MAPREDUCE-6693:
-------------------------------------------
Good catch. Thanks for trying fixing the issue.
{code}
if (encodedString.length() <= limitLength)
{code}
and
{code}
index + increase >= limitLength
{code}
make sense.
About adding
{code}
index + increase >= strBytes.length
{code}
I don't disagree but I wonder are there any possibility that index + increase
>= strBytes.length.
If the size of strArray is less than 50, e.g. 49, encodedString.length() is 49,
means encodingString.length() <= 50 so trimURLEncodingString method will return
in
{code}
if (encodedString.length() < limitLength) {
return encodedString;
}
{code}
If I miss something, please correct me.
